Limits of Meritocracy. How Fields of Study and Gender Segregation Affect Social Stratification in Finland

This dissertation critically reviews the idea of meritocracy from both a theoretical and an empirical perspective. Based on a discussion of classical texts of social philosophy and sociology, it is argued that meritocracy as a concept for social stratification is best compatible with the sociological tradition of status attainment research: both frame social inequality in primarily individualistic terms, centring on the role of ascribed (e.g., gender, social background) and achieved (e.g., educational qualifications) characteristics for determining individuals’ socioeconomic rewards. This theoretical argument introduces the research problem at the core of this dissertation: to what extent can the individualistic conception of social stratification be maintained empirically? Fields of study and their interaction with educational attainment levels play a prominent role in the analysis of this question. Drawing on sociological versions of segmented labour market theory, it is assumed that fields of study may channel individuals into heterogeneous political-economic contexts on the labour market, which potentially modify the socioeconomic benefit individuals derive from their qualification levels. The focus on fields of study may also highlight economic differentials between men and women that derive from the persisting segregation of men’s and women’s occupational and educational specializations rather than direct gender discrimination on the labour market. The quantitative analyses in this dissertation consist of three research articles, which are based primarily on Finnish data, but occasionally extend the view to other European countries. The data sources include register-based macro- and microdata as well as survey data. Article I examines the extent and the patterns of gender segregation within the Finnish educational system between 1981 and 2005. The results show that differences between men’s and women’s field specializations have for the most part remained stable during this period, with particularly high levels of gender segregation observed at lower educational levels. The focus in Article II rests on the effects of gender-segregated fields of study on higher education graduates’ occupational status. It is shown that fields of study matter for accessing professional jobs and avoiding low-skilled positions in Finland: at the early career stage, particularly polytechnic graduates from female-dominated fields are less likely to work in professional positions. Finnish university graduates from male-dominated fields were more likely than their peers with different specializations to work as professionals, yet they also faced a greater risk of being sorted into lowskilled jobs if they failed to make use of this advantage. Article III proceeded to analyse the joint impact of educational qualification levels and fields of study on young adults’ median earnings in Finland between 1985 and 2005. The results show that qualification levels do not confer a consistent benefit in the process of earnings stratification. Advanced qualifications raise median earnings most clearly among individuals specializing in the same field of study. When comparing individuals with different field specializations, on the other hand, higher-level qualifications do not necessarily lead to higher median earnings. Overall, the findings of this dissertation reveal a heterogeneous effect of education for achieving social positions, which challenges individual-centred, meritocratic accounts of social stratification and underlines the problematic lack of structural and institutional dimensions in the dominant account of social status attainment.

Transforming Bodies, Wandering Desires. Intra-actions of Gender and Sexuality in Non-heterosexual Transgender Embodiment

Pro gradu -tutkielmani käsittelee sukupuolen ja seksuaalisuuden keskinäisiä intraaktiivisia vuorovaikutussuhteita elettyjen, ei-heteroseksuaalisten transsukupuolisten ruumiiden kokemuksissa. Tutkielmani haastaa sukupuolen ja seksuaalisuuden pysyvyyden käsityksiä sekä niihin liittyviä yhteiskunnallisia normeja kuvaten tapoja, joilla seksuaalisuuden ja sukupuolen kokeminen ja käytännöt liikkuvat, kehittyvät ja vuorovaikuttavat eletyissä transsukupuolisuuden ruumiillistumissa. Haastattelen kuutta suomalaista, syntymässä naiseksi määriteltyä transsukupuolista henkilöä liittyen heidän kokemuksiinsa sukupuolesta, seksuaalisuudesta ja näiden muutoksista heidän tähänastisen elämänsä aikana. Tarkastelen nauhoitettuja ja litteroituja haastattelutekstejä transtutkimusta, queer-teoriaa ja feminististä uusmaterialistista filosofiaa yhdistävän teoreettisen kehyksen kautta keskittyen siihen, miten sukupuoli ja seksuaalisuus vaikuttavat toistensa kehitykseen, muutokseen ja materialisoitumiseen eri elämänvaiheissa ja tilanteissa. Erityisen tärkeiksi teoreettisiksi vaikuttajiksi tutkielmassani muodostuvat Judith Butlerin Gender Trouble (2006 [1990]) -teoksessaan hahmottelema performatiivisen sukupuolen teoria, Sara Ahmedin analyysi teoksessa Queer Phenomenology. Orientations, Objects, Others (2006) ja Karen Baradin teoksessa Meeting the Universe Halfway. Quantum Physics and the Entanglement of Matter and Meaning (2007) teoretisoima toimijuudellinen realismi. Päästäkseni kiinni sukupuolen ja seksuaalisuuden yhtymäkohtiin erittelen ensin niitä ominaisuuksia ja kokemuksia, jotka näyttäytyvät haastatteluteksteissäni oleellisina seksuaalisuuden ja sukupuolen kannalta. Tarkastelen seksuaalisuutta suuntautumisen, halun ja seksuaalisten käytäntöjen näkökulmasta: vaikka nämä seksuaalisuuden aspektit ovat kiinteästi kytköksissä toisiinsa, niitä ei voi kokonaan palauttaa toisiinsa. Sukupuolta käsittelen performatiivisuuden näkökulmasta painottaen transsukupuolisiin ruumiisiin ja niiden materiaalisuuteen liittyviä erityispiirteitä. Sukupuolen ja seksuaalisuuden suhteita toisiinsa tarkastelen sekä sellaisissa tilanteissa, joissa niitä on vaikea erottaa toisistaan, että sellaisissa, joissa niiden voidaan nähdä tuottavan toinentoisiaan. Tutkielmallani on etnografisia, filosofisia ja poliittisia ulottuvuuksia. Yhtäältä tahdon kuvata ja analysoida elettyjä transsukupuolisia kokemuksia ja tuottaa tietoa vähän tutkitun ihmisryhmän todellisuudesta. Toisaalta osallistun sukupuolifilosofiseen keskusteluun ruumiillisuudesta ja sukupuolen ja seksuaalisuuden olemuksesta. Lähestyn tutkimusprosessiani niin sanotusta transgender standpoint -näkökulmasta; kirjoitan transsukupuolisena ruumiina, transsukupuolisia ruumiita koskien, pyrkimyksenäni edistää elävien transsukupuolisten ruumiiden asemaa, toimijuutta ja näkyvyyttä yhteiskunnassa.

Diagnosing Gender: Transitivity Analysis on the Diagnostic Category of Gender Dysphoria in DSM-5

Tässä tutkielmassa analysoidaan teoksessa ’Diagnostic and Statistical Manual of Men-tal Disorders, Fifth Edition’ (DSM-5) ja tarkemmin sen kappaleessa ’Gender Dysphoria’ käytettyä kieltä. DSM-5 on mielenterveydenalan ammattilaisille suunnattu luokittelu virallisesti tunnustetuista mielenterveyden häiriöistä ja se sisältää myös oireiden kuvai-luun perustuvat ohjeet näiden mielenterveyshäiriöiden diagnosoimiseksi. ’Gender dys-phoria’ (vapaasti suomennettuna sukupuolidysforia) on lääketieteellinen termi, joka viittaa biologisesta sukupuolesta eriävän sukupuoli-identiteetin aiheuttamaan henki-seen pahoinvointiin. Sukupuoli-identiteetin ja mielenterveysongelman yhdistäminen sisältää ideologisiin arvoihin pohjautuvia perusteluja ja tässä tutkielmassa analysoi-daan ’Gender Dysphoria’ – kappaleen ideologista sisältöä kriittisestä näkökulmasta. Tutkimuksen tarkastellaan ’Gender Dysphoria’ – kappaleessa käytetyn kielen ideologi-sia heijastumia ja niiden sosiaalisia vaikutuksia kolmen tutkimuskysymyksen avulla: 1) Kuinka diagnosoitu henkilö esitetään tekstissä? 2) Kuinka tekstissä rakennetaan kuvaa sukupuolidysforiasta mielenterveyshäiriönä? 3) Miten analyysin tulokset saattavat vai-kuttaa käsitykseen sukupuolen yhteydestä mielenterveyteen ja sukupuolidysforian diagnosoimiseen. Analyysissä käytetään metodina M. A. K. Hallidayn transitiivisuusteo-riaa ja tulosten sosiaalisia vaikutuksia analysoidaan Norman Faircloughn diskurssiana-lyysimallin avulla. Transitiivisuusanalyysin avulla tarkastellaan kirjoittajien tekemiä va-lintoja kielenkäytön suhteen, jotka Hallidayn teorian mukaan heijastavat kirjoittajien henkilökohtaisia kokemuksia ympäröivästä maailmasta. Tutkimus paljasti, että sukupuolidysforia esitetään mielenterveysongelmana erotta-malla se yksilöstä erilliseksi toimijaksi, joka suorittaa erilaisia prosesseja yksilön sisällä. Yksilöistä erityisesti lapset esitetään tekstissä voimakkaasti perinteisiin sukupuoliroo-leihin pohjautuvan ideologian valossa, joka heijastuu oireiden kuvailuun. Analyysi osoittaa myös logiikkaongelmia lasten oireiden kuvailussa, jotka johtavat ristiriitoihin oireiden ja mielenterveysongelman yhteydessä ja kumoavat perusteet, joiden pohjalta lapset diagnosoidaan. Tutkimuksen lopussa ehdotetaan, että sukupuolidysforiaan liit-tyvien diagnoosiohjeiden ja – kriteerien perusteita muokataan yleisesti sukupuoli-identiteetin itsemääräämisoikeuteen pohjautuvaksi ja lasten osalta tekstiin sisällytet-täisiin mahdollisia tieteellisiä perusteluja, jotka kumoaisivat diagnoosiohjeiden nyky-muodossaan sisältämät ristiriidat ja perustelisivat lasten diagnosoinnin oikeellisuuden

Gender effects on esophageal motility

It has been suggested that there are no gender effects on esophageal motility. However, in previous studies the subjects did not perform multiple swallows and the quantitative features of esophageal contractions were not evaluated. In order to investigate the gender effects on esophageal motility we studied 40 healthy normal volunteers, 20 men aged 37 ± 15 years (mean ± SD), and 20 women aged 38 ± 14 years. We used the manometric method with an eight-lumen polyvinyl catheter and continuous perfusion. The upper and lower esophageal sphincter pressures were measured by the rapid pull-through method. With the catheter positioned with one lumen opening in the lower esophageal sphincter, and the others at 5, 10 and 15 cm above the sphincter, ten swallows of a 5-ml water bolus alternated with ten dry swallows were performed. Statistical analysis was done by the Student t-test and Mann-Whitney test. Gender differences (P<0.05) were observed for wet swallows in the duration of contractions 5 cm above the lower esophageal sphincter (men: 3.7 ± 0.2 s, women: 4.5 ± 0.3 s, mean ± SEM), and in the velocity of contractions from 15 to 10 cm above the lower esophageal sphincter (men: 4.7 ± 0.3 cm/s, women: 3.5 ± 0.2 cm/s). There was no difference (P>0.05) in sphincter pressure, duration and percentage of complete lower esophageal sphincter relaxation, amplitude of contractions, or in the number of failed, multipeaked and synchronous contractions. We conclude that gender may cause some differences in esophageal motility which, though of no clinical significance, should be taken into consideration when interpreting esophageal motility tests.

Gender differences in the activities of aspirin-esterases in rat tissues

The activities of aspirin (acetylsalicylic acid)-esterases were measured in several tissues (liver, kidney, adrenal glands, brain and serum) from adult male and female Wistar rats. In males, both aspirin-esterase I (assayed at pH 5.5) and II (assayed at pH 7.4) activities were higher in liver homogenates when compared to females (aspirin-esterase I: males 48.9 ± 4.8 (N = 8) and females 29.3 ± 4.2 (N = 8) nmol of salicylic acid formed min-1 mg protein-1; aspirin-esterase II: males 41.4 ± 4.1 (N = 8) and females 26.1 ± 4.5 (N = 8) nmol of salicylic acid formed min-1 mg protein-1, P<0.001). In serum, enzyme activity was higher in females than in males (aspirin-esterase I: males 0.85 ± 0.06 (N = 6) and females 1.18 ± 0.11 (N = 6) nmol of salicylic acid formed min-1 mg protein-1; aspirin-esterase II: males 1.03 ± 0.13 (N = 6) and females 1.34 ± 0.11 (N = 6) nmol of salicylic acid formed min-1 mg protein-1, P<0.001). In the other tissues assayed, no statistically significant difference between males and females was found. There were no statistically significant differences when the enzymes were assayed in different phases of the estrous cycle in liver and serum. These results show that the differences in aspirin-esterase activity observed between males and females are not due to the estrous cycle. The gender difference obtained in our study may indicate an involvement of gonadal hormones in the control of the hydrolysis of aspirin. This possibility is currently under investigation.

Gender differences in vascular expression of endothelin and ET A/ET B receptors, but not in calcium handling mechanisms, in deoxycorticosterone acetate-salt hypertension

We determined if the increased vascular responsiveness to endothelin-1 (ET-1) observed in male, but not in female, DOCA-salt rats is associated with differential vascular mRNA expression of ET-1 and/or ET A/ET B receptors or with functional differences in Ca2+ handling mechanisms by vascular myocytes. Uninephrectomized male and female Wistar rats received DOCA and drinking water containing NaCl/KCl. Control rats received vehicle and tap water. Blood pressure and contractile responses of endothelium-denuded aortic rings to agents which induce Ca2+ influx and/or its release from internal stores were measured using standard procedures. Expression of mRNA for ET-1 and ET A/ET B receptors was evaluated by RT-PCR after isolation of total cell RNA from both aorta and mesenteric arteries. Systolic blood pressure was higher in male than in female DOCA rats. Contractions induced by Bay K8644 (which activates Ca2+ influx through voltage-operated L-type channels), and by caffeine, serotonin or ET-1 in Ca2+-free buffer (which reflect Ca2+ release from internal stores) were significantly increased in aortas from male and female DOCA-salt compared to control aortas. DOCA-salt treatment of male, but not female, rats statistically increased vascular mRNA expression of ET-1 and ET B receptors, but decreased the expression of ET A receptors. Molecular up-regulation of vascular ET B receptors, rather than differential changes in smooth muscle Ca2+ handling mechanisms, seems to account for the increased vascular reactivity to ET-1/ET B receptor agonists and higher blood pressure levels observed in male DOCA-salt rats.

Gender-related differences in the effects of nitric oxide donors on neuroleptic-induced catalepsy in mice

It has been suggested that nigrostriatal dopaminergic transmission is modulated by nitric oxide (NO). Since there is evidence that gonadal hormones can affect extrapyramidal motor behavior in mammals, we investigated the effects of isosorbide dinitrate (ISD), linsidomine (SIN-1) and S-nitroso-N-acetylpenicillamine (SNAP), three pharmacologically different NO donors, on neuroleptic-induced catalepsy in 60- to 80-day-old male and female albino mice. Catalepsy was induced with haloperidol (1 mg/kg, ip) and measured at 30-min intervals by means of a bar test. Drugs (or appropriate vehicle) were injected ip 30 min before haloperidol, with each animal being used only once. ISD (5, 20 and 50 mg/kg) caused a dose-dependent inhibition of catalepsy in male mice (maximal effect 120 min after haloperidol: 64% inhibition). In the females only at the highest dose of ISD was an attenuation of catalepsy observed, which was mild and short lasting. SIN-1 (10 and 50 mg/kg) did not significantly affect catalepsy in female mice, while a significant attenuation was observed in males at the dose of 50 mg/kg (maximal inhibition: 60%). SNAP (20 mg/kg) significantly attenuated catalepsy in males 120 min after haloperidol (44% inhibition), but had no significant effect on females. These results basically agree with literature data showing that NO facilitates central dopaminergic transmission, although the mechanisms are not fully understood. They also reveal the existence of gender-related differences in this nitrergic modulation in mice, with females being less affected than males.

Transition management in action within the context of nutrient economy

Tämä työ tutkii ja tarkastelee transitio-kokeilua ravinnetaloudessa. Transitio-kokeilu on toimintatutkimusprojekti, joka toteutetaan systeemisen muutoksen ajattelun mukaisesti alhaalta ylöspäin. Ravinnetalous määritetään tarkemmin työn kautta sekä analysoidaan monitaso-perspektiivin näkökulmasta. Ravinnetalous on terminä varsin tuntematon ja tarvitsee enemmän tunnettavuutta laajemman yleisön edessä. Transitio-areenan ja transitio-visioiden kehittäminen ovat työn keskipisteessä, koska ne ovat tärkeimpiä vaiheita transition alkuvaiheessa. Joukko sidosryhmätoimijoita osallistuu transitio areenaan sekä visioiden jatkokehittelyyn. Visio(t) luodaan ensisijaisesti backcasting-menetelmällä, jota myös täydennetään tavanomaisella ennustamisella. Backcasting- menetelmä on osin osallistava ja siinä käytetään ravinteiden planeettarajoja kvantitatiivisina pääperiaatteina, minkä tuloksena myös visiot ovat osin kvantitatiivisia. Transitio areenan kokoaminen ja fasilitointi aiheuttavat hankalia kysymyksiä, jotka tarvitsevat jatko-tutkimusta. Alhaalta-ylöspäin organisoitu transitio-arena houkuttelee niche-toimijoita, mutta epäonnistuu sitouttamaan julkisen vallan toimijoita. Toimintamallin voimasuhteet, politiikka ja transition vakiinnuttaminen tulisivat olla jatko-toimenpiteinä niin tutkimuksessa kuin toiminnassakin.

Category fluency test: effects of age, gender and education on total scores, clustering and switching in Brazilian Portuguese-speaking subjects

Verbal fluency tests are used as a measure of executive functions and language, and can also be used to evaluate semantic memory. We analyzed the influence of education, gender and age on scores in a verbal fluency test using the animal category, and on number of categories, clustering and switching. We examined 257 healthy participants (152 females and 105 males) with a mean age of 49.42 years (SD = 15.75) and having a mean educational level of 5.58 (SD = 4.25) years. We asked them to name as many animals as they could. Analysis of variance was performed to determine the effect of demographic variables. No significant effect of gender was observed for any of the measures. However, age seemed to influence the number of category changes, as expected for a sensitive frontal measure, after being controlled for the effect of education. Educational level had a statistically significant effect on all measures, except for clustering. Subject performance (mean number of animals named) according to schooling was: illiterates, 12.1; 1 to 4 years, 12.3; 5 to 8 years, 14.0; 9 to 11 years, 16.7, and more than 11 years, 17.8. We observed a decrease in performance in these five educational groups over time (more items recalled during the first 15 s, followed by a progressive reduction until the fourth interval). We conclude that education had the greatest effect on the category fluency test in this Brazilian sample. Therefore, we must take care in evaluating performance in lower educational subjects.

Gender-related pathways for behavior problems in the offspring of alcoholic fathers

The objective of the present study was to examine gender differences in the influence of paternal alcoholism on children's social-emotional development and to determine whether paternal alcoholism is associated with a greater number of externalizing symptoms in the male offspring. From the Mannheim Study of Risk Children, an ongoing longitudinal study of a high-risk population, the developmental data of 219 children [193 (95 boys and 98 girls) of non-alcoholic fathers, non-COAs, and 26 (14 boys, 12 girls) of alcoholic fathers, COAs] were analyzed from birth to the age of 11 years. Paternal alcoholism was defined according to the ICD-10 categories of alcohol dependence and harmful use. Socio-demographic data, cognitive development, number and severity of behavior problems, and gender-related differences in the rates of externalizing and internalizing symptoms were assessed using standardized instruments (IQ tests, Child Behavior Checklist questionnaire and diagnostic interviews). The general linear model analysis revealed a significant overall effect of paternal alcoholism on the number of child psychiatric problems (F = 21.872, d.f. = 1.217, P < 0.001). Beginning at age 2, significantly higher numbers of externalizing symptoms were observed among COAs. In female COAs, a pattern similar to that of the male COAs emerged, with the predominance of delinquent and aggressive behavior. Unlike male COAs, females showed an increase of internalizing symptoms up to age 11 years. Of these, somatic complaints revealed the strongest discriminating effect in 11-year-old females. Children of alcoholic fathers are at high risk for psychopathology. Gender-related differences seem to exist and may contribute to different phenotypes during development from early childhood to adolescence.

Effect of age and gender on sweat lactate and ammonia concentrations during exercise in the heat

The dependence of sweat composition and acidity on sweating rate (SR) suggests that the lower SR in children compared to adults may be accompanied by a higher level of sweat lactate (Lac-) and ammonia (NH3) and a lower sweat pH. Four groups (15 girls, 18 boys, 8 women, 8 men) cycled in the heat (42ºC, 20% relative humidity) at 50% VO2max for two 20-min bouts with a 10-min rest before bout 1 and between bouts. Sweat was collected into plastic bags attached to the subject's lower back. During bout 1, sweat from girls and boys had higher Lac- concentrations (23.6 ± 1.2 and 21.2 ± 1.7 mM; P < 0.05) than sweat from women and men (18.2 ± 1.9 and 14.8 ± 1.6 mM, respectively), but Lac- was weakly associated with SR (P > 0.05; r = -0.27). Sweat Lac- concentration dropped during exercise bout 2, reaching similar levels among all groups (overall mean = 13.7 ± 0.4 mM). Children had a higher sweat NH3 than adults during bout 1 (girls = 4.2 ± 0.4, boys = 4.6 ± 0.6, women = 2.7 ± 0.2, and men = 3.0 ± 0.2 mM; P < 0.05). This difference persisted through bout 2 only in females. On average, children's sweat pH was lower than that of adults (mean ± SEM, girls = 5.4 ± 0.2, boys = 5.0 ± 0.1, women = 6.2 ± 0.5, and men = 6.2 ± 0.4 for bout 1, and girls = 5.4 ± 0.2, boys = 6.5 ± 0.5, women = 5.2 ± 0.2, and men = 6.9 ± 0.4 for bout 2). This may have favored NH3 transport from plasma to sweat as accounted for by a significant correlation between sweat NH3 and H+ (r = 0.56). Blood pH increased from rest (mean ± SEM; 7.3 ± 0.02) to the end of exercise (7.4 ± 0.01) without differences among groups. These results, however, are representative of sweat induced by moderate exercise in the absence of acidosis.

Breathing disorders in congestive heart failure: gender, etiology and mortality

We investigated the relationship between sleep-disordered breathing (SDB) and Cheyne-Stokes respiration (CSR) while awake as well as mortality. Eighty-nine consecutive outpatients (29 females) with congestive heart failure (CHF; left ventricular ejection fraction, LVEF <45%) were prospectively evaluated. The presence of SDB and of CSR while awake before sleep onset was investigated by polysomnography. SDB prevalence was 81 and 56%, using apnea-hypopnea index cutoffs >5 and >15, respectively. CHF etiologies were similar according to the prevalence of SDB and sleep pattern. Males and females were similar in age, body mass index, and LVEF. Males presented more SDB (P = 0.01), higher apnea-hypopnea index (P = 0.04), more light sleep (stages 1 and 2; P < 0.05), and less deep sleep (P < 0.001) than females. During follow-up (25 ± 10 months), 27% of the population died. Non-survivors had lower LVEF (P = 0.01), worse New York Heart Association (NYHA) functional classification (P = 0.03), and higher CSR while awake (P < 0.001) than survivors. As determined by Cox proportional model, NYHA class IV (RR = 3.95, 95%CI = 1.37-11.38, P = 0.011) and CSR while awake with a marginal significance (RR = 2.96, 95%CI = 0.94-9.33, P = 0.064) were associated with mortality. In conclusion, the prevalence of SDB and sleep pattern of patients with Chagas' disease were similar to that of patients with CHF due to other etiologies. Males presented more frequent and more severe SDB and worse sleep quality than females. The presence of CSR while awake, but not during sleep, may be associated with a poor prognosis in patients with CHF.

Influence of gender on psychomotor vigilance task performance by adolescents

During adolescence, the sleep phase delay associated with early school times increases daytime sleepiness and reduces psychomotor performance. Some studies have shown an effect of gender on psychomotor performance in adults and children. Males present faster reaction times (RT) compared with females. The aim of the present study was to evaluate the influence of gender on Palm psychomotor vigilance task (PVT) performance in adolescents. Thirty-four adolescents (19 girls, 13 to 16 years old) attending morning school classes of a public school in Curitiba, PR, Brazil, participated in the study. Sleep patterns were measured using actigraphy and sleepiness data were accessed with the Karolinska Sleepiness Scale (KSS). KSS and PVT measurements were collected at two times in the morning (8:00 and 11:00 h). The data were compared using one-way ANOVA, considering gender as a factor. ANOVA indicated that gender did not affect sleep patterns and subjective somnolence; however, a statistically significant effect of gender was detected for PVT performance. Boys presented faster RT (RT-PVT1: 345.51 ms, F = 6.08, P < 0.05; RT-PVT2: 343.30 ms, F = 6.35, P < 0.05) and fewer lapses (lapses-PVT1: 8.71, F = 4.45, P < 0.05; lapses-PVT2: 7.82, F = 7.06, P < 0.05) compared with girls (RT-PVT1: 402.96; RT-PVT2: 415.70; lapses-PVT1: 16.33; lapses-PVT2: 17.80). These results showed that this effect of gender, already reported in adults and children, is also observed in adolescents. The influence of gender should be taken into account in studies that use Palm PVT to evaluate psychomotor performance in this age range.
