Separable neural components in the processing of black and white faces

In a study of the neural components of automatic and controlled social evaluation, White participants viewed Black and White faces during event-related functional magnetic resonance imaging. When the faces were presented for 30 ms, activation in the amygdala-a brain region associated with emotion-was greater for Black than for White faces. When the faces were presented for 525 ms, this difference was significantly reduced, and regions of frontal cortex associated with control and regulation showed greater activation for Black than White faces. Furthermore, greater race bias on an indirect behavioral measure was correlated with greater difference in amygdala activation between Black and White faces, and frontal activity predicted a reduction in Black-White differences in amygdala activity from the 30-ms to the 525-ms condition. These results provide evidence for neural distinctions between automatic and more controlled processing of social groups, and suggest that controlled processes may modulate automatic evaluation.     

Visual attention and word recognition in stroop color naming: is word recognition "automatic"?

In Stroop color naming, color targets were accompanied by a color word or a color word plus a neutral word that reduces or "dilutes" the Stroop effect. Abrupt-onset cues called the focus of attention to one stimulus or another. Cuing influenced the size of the Stroop effect but never eliminated it. Unlike the Stroop effect itself, Stroop dilution from the neutral word could be eliminated, by cuing the color word. Focusing visual attention on the color word protected it from Stroop dilution; focusing visual attention on the neutral word did not prevent Stroop interference. Thus, spatial attention is a modulator, protecting visual data from crosstalk, but a word need not be the focus of visual attention to be recognized.     

Acting in our interests: Relational self-construal and goal motivation across cultures

Relationally-autonomous reasons (RARs) are motives for behavior that take into account one’s close relationships. A cross-cultural model tested the hypotheses that (a) people with a highly relational self-construal will pursue their goals for RARs, and (b) RARs will predict positive goal outcomes after controlling for variance explained by personally-autonomous reasons (PARs) and social support. One hundred seventy Americans and 219 Japanese completed a well-being and self questionnaire then generated and rated seven goals on several attributes. Results showed that relational self-construal was associated with RARs for goals. RARs predicted effort directly and predicted progress and purpose in life indirectly for both groups. In addition, Americans and Japanese differed in the types of goals they pursued and the degree to which social support predicted effort. Implications for self, culture, and motivation research are discussed.

Individual differences that moderate the effectiveness of relational reasons for self-improvement

Two studies tested the hypotheses that relationally-autonomous reasons (RARs) for goals predict attainment, and that this relationship is stronger among highly relational and agreeable people than others. Study 1 (n = 134) assessed participants’ self-construal and Agreeableness, and their tendency to pursue subgoals for RARs, relationally-controlled reasons (RCRs), and personally-controlled reasons (PARs). One month later, they indicated the number of subgoals they had attained. RARs were positively correlated with attainment, and this relationship was stronger among highly relational and agreeable people than others. In Study 2 (n = 74), self-construal and Agreeableness were assessed then participants generated possible outcomes of 3 subgoals using a Goal Attainment Scale. They were then randomly assigned to a goal program that either emphasized RARs, RCRs, or PARs. One week later, participants indicated their level of attainment. Highly relational and agreeable people had higher levels of attainment than others in the program emphasizing RARs.     

Visual extinction and awareness: The importance of binding dorsal and ventral pathways

Patients with visual extinction were tested on three tasks involving stimulus identification and localization. In the first experiment, in which patients were to identify and localize stimuli, they demonstrated high levels of contralesional omissions. This primarily occurred under conditions of double simultaneous stimulation (DSS), consistent with the character of extinction. In contrast, when patients had to simply localize or count stimuli in Experiment 2, their contralesional omissions were very low. Similarly, when patients were to identify stimuli without localizing them (Experiment 3) they again showed very low contralesional error rates. These results support the view (Baylis, Driver, & Rafal, 1993) that visual extinction may be greatest when information about location cannot be bound to information about identity.     

Effects of naloxone on acquisition and extinction of jump-up avoidance behavior in rats

Two experiments were carried out to assess the effects of the opioid antagonist, naloxone, on the acquisition and extinction of shock avoidance by rats in the jump-up apparatus. In Experiment 1 naloxone pretreatment facilitated acquisition but had no effect on extinction of avoidance behavior. In the second experiment the effect of naloxone on acquisition was replicated and in addition, it was shown that naloxone enhanced freezing when a response prevention or flooding procedure was introduced. Again naloxone failed to alter the course of extinction, nor did it interact with the effects of flooding which, by itself, facilitated extinction. The results suggest that naloxone's effects are limited to increasing the functional intensity of the US, and provide further support for the dissociation between extinction of avoidance behavior and other indices of fear.     

Structural examination of RIASEC scales in high school students: Variation across ethnicity and method

The structural validity of Holland’s model of vocational interests across racial/ethnic groups was examined in the population of high school juniors in two states. The fit of the circumplex model to Holland’s RIASEC types as assessed by the UNIACT-R was evaluated for the general sample and five subgroups: Caucasian/Euro-Americans, African Americans, Asian Americans, Latinos, and Native Americans. Four different methods were used to test the proposed circumplex structure, each with various circumplex definitions. Results indicate that nonparametric methods generally showed good model-data fit, whereas SEM-based results indicated less support. No differences in fit were found across ethnicity supporting the usage with U.S. ethnic groups.     

The link between time orientation and religious orientation among American college students

The purpose of this study was to explore how an individual’s religion relates to their time orientation. Specifically, we hypothesised (a) intrinsic orientation would positively correlate with future orientation, (b) extrinsic orientation would positively correlate with present-hedonistic orientation, (c) quest orientation would positively correlate with present-hedonistic and future orientations, (d) orthodox orientation would positively correlate with past positive orientation, and (e) secularism would positively correlate with past negative orientation, present-fatalistic and future orientations. Participants (n?=?150) completed an online survey of time orientation and religious orientation. The results showed that perceptions of the past are strongly linked to religious orientation, with more positive perceptions being linked to the more traditional orientations, and less positive perceptions linked to the looser and secularist orientations.
