Cognitive set, absorption, and achievement as moderators of the perceptual closure effect in picture priming /

The present study examined individual differences in Absorption and fantasy, as well as in Achiievement and achievement striving as possible moderators of the perceptual closure effect found by Snodgrass and Feenan (1990). The study also examined whether different instructions (experiential versus instrumental) interact with the personality variables to moderate the relationship between priming and subsequent performance on a picture completion task. 1 28 participants completed two sessions, one to fill out the MPQ and NEO personality inventories and the other to complete the experimental task. The experimental task consisted of a priming phase and a test phase, with pictures presented on a computer screen for both phases. Participants were shown 30 pictures in the priming phase, and then shovm the 30 primed pictures along with 30 new pictures for the test phase. Participants were randomly assigned to receive one of the two different instruction sets for the task. Two measures of performance were calculated, most fragmented measure and threshold. Results of the present study confirm that a five-second exposure time is long enough to produce the perceptual closure effect. The analysis of the two-way interaction effects indicated a significant quadratic interaction of Absorption with priming level on threshold performance. The results were in the opposite direction of predictions. Possible explanations for the Absorption results include lack of optimal conditions, lack of intrinsic motivation and measurement problems. Primary analyses also revealed two significant between-subject effects of fantasy and achievement striving on performance collapsed across priming levels. These results suggest that fantasy has a beneficial effect on performance at test for pictures primed at all levels, whereas achievement striving seems to have an adverse effect on performance at test for pictures primed at all levels. Results of the secondary analyses with a revised threshold performance measure indicated a significant quadratic interaction of Absorption, condition and priming level. In the experiential condition, test performance, based on Absorption scores for pictures primed at level 4, showed a positive slope and performance for pictures primed at levels 1 and 7 based on Absorption showed a negative slope. The reverse effect was found in the instrumental condition. The results suggest that Absorption, in combination with experiential involvement, may affect implicit memory. A second significant result of the secondary analyses was a linear three-way interaction of Achievement, condition and priming level on performance. Results suggest that as Achievement scores increased, test performance improved for less fragmented primed pictures in the instrumental condition and test performance improved for more highly fragmented primes in the experiential condition. Results from the secondary analyses suggest that the revised threshold measure may be more sensitive to individual differences. Results of the exploratory analyses with Openness to Experience, Conscientiousness and agentic positive emotionality (PEM-A) measures indicated no significant effects of any of these personality variables. Results suggest that facets of the scales may be more useful with regard to perceptual research, and that future research should examine narrowly focused personality traits as opposed to broader constructs.

The Co-occurrence of Depressive Symptoms and Alcohol Use for Adolescent Boys and Girls: An Investigation of the Role of Self-Regulation and Approach Behavior

While many studies have been conducted on adolescent depressive symptoms and alcohol use, much of the research has examined these behaviors separately rather than examining their co-occurrence within individuals. In the present study, adolescents (N = 4412; 49% female) were surveyed at four time points (grade 9, 10, 11, and 12) and growth mixture modeling was used to identify groups of individuals reporting various patterns of depressive symptoms and alcohol use across the high school years. Four groups were identified, including co-occurrence (higher depressive symptoms and higher alcohol use relative to peers, comprising 6.1 % of boys and 7.1 % of the girls in the sample), pure depressive symptoms (higher depressive symptoms and lower alcohol use; 12.7% of boys and 12.5% of girls), pure alcohol use (higher alcohol use and lower depressive symptoms; 20.9% of boys and 19.9% of girls), and low co-occurrence (lower depressive symptoms and alcohol use, 60.3% of boys and 60.5% of girls). Groups were compared on self-regulatory (i.e., delay of gratification) and approach behaviors. For both boys and girls, delay of gratification was the strongest predictor of group membership, with the co-occurrence group scoring the lowest and the low co-occurrence group the highest. This finding emphasizes the importance of assessing delay of gratification in the identification of high risk youth.

The Ligand and Membrane-binding Behaviour of the Phosphatidylinositol Transfer Proteins (PITPa & PITPb)

Human Class I phosphatidylinositol transfer proteins (PITPs) exists in two forms: PITPα and PITPβ. PITPs are believed to be lipid transfer proteins based on their capacity to transfer either phosphatidylinositol (PI) or phosphatidylcholine (PC) between membrane compartments in vitro. In Drosophila, the PITP domain is found to be part of a multi-domain protein named retinal degeneration B (RdgBα). The PITP domain of RdgBα shares 40 % sequence identity with PITPα and has been shown to possess PI and PC binding and transfer activity. The detailed molecular mechanism of ligand transfer by the human PITPs and the Drosophila PITP domain remains to be fully established. Here, we investigated the membrane interactions of these proteins using dual polarization interferometry (DPI). DPI is a technique that measures protein binding affinity to a flat immobilized lipid bilayer. In addition, we also measured how quickly these proteins transfer their ligands to lipid vesicles using a fluorescence resonance energy transfer (FRET)-based assay. DPI investigations suggest that PITPβ had a two-fold higher affinity for membranes compared to PITPα. This was reflected by a four-fold faster ligand transfer rate for PITPβ in comparison to PITPα as determined by the FRET assay. Interestingly, DPI analysis also demonstrated that PI-bound human PITPs have lower membrane affinity compared to PC-bound PITPs. In addition, the FRET studies demonstrated the significance of membrane curvature in the ligand transfer rate of PITPs. The ligand transfer rate was higher when the accepting vesicles were highly curved. Furthermore, when the accepting vesicles contained phosphatidic acid (PA) which have smaller head groups, the transfer rate increased. In contrast, when the accepting vesicles contained phosphoinositides which have larger head groups, the transfer rate was diminished. However, PI, the favorite ligand of PITPs, or the presence of anionic lipids did not appear to influence the ligand transfer rate of PITPs. Both DPI and FRET examinations revealed that the PITP domain of RdgBα was able to bind to membranes. However, the RdgBα PITP domain appears to be a poor binder and transporter of PC.
