Sociotropy and autonomy: the nature of vulnerability

Sociotropy and autonomy are 2 personality dimensions related to an individual's vulnerability to depression (A. T. Beck, 1983). The Sociotropy-Autonomy Scale (D. A. Clark, R. A. Steer, A. T. Beck, & L. Ross, 1995) and the Personal Style Inventory (C. J. Robins et al., 1994) were developed to assess these personality dimensions independent of each other. The present study is an examination of the relationship between the 2 scales and an attempt to specify the various factors that emerge when the items of the 2 scales are integrated. Participants (N = 514) responded to the Personal Style Inventory, the Sociotropy-Autonomy Scale, and the Beck Depression Inventory (A. T. Beck & R. A. Steer, 1987). A principal component analysis on all of the items of the 2 scales revealed a four-factor structure (2 sociotropy and 2 autonomy). The author examined the relationships between depression, the 4 factors, and the 2 original scales and discussed the results in the context of vulnerability to depression.     

Developmental order driving the relationship between executive functions and theory of mind: a case study

Several studies have suggested there is a developmental link between executive functions and theory of mind. However, the developmental order driving the relationship is not well understood. The main reason is that the development of executive function parallels the development of theory of mind in normally developing children. In this paper, a case (H.Y.) is reported. H.Y. had lived in a persistent vegetative state for 6 years after encephalitis at the age of 10. He showed a developmental order driving the relationship between executive functions and theory of mind. These findings are consistent with recent suggestions that development of executive function might be important as a predecessor of either the ability to understand false beliefs or the ability to express that understanding.     

Significance of visual cues in choice behavior in the female zebra finch (<Emphasis Type="Italic">Taeniopygia guttata</Emphasis><Emphasis Type="Italic">castanotis</Emphasis>)

Female zebra finches show a preference for male zebra finches over heterospecific males based solely on the auditory cues of males, such as songs. The present study was designed to investigate whether females show a similar preference for male zebra finches based solely on visual cues. Using a Y-maze apparatus, social preference of female zebra finches was studied between male zebra finches and male Bengalese finches in three experiments. In experiment 1, where female zebra finches could see and hear live male zebra finches and male Bengalese finches, the females preferred to associate with the male zebra finches. In experiment 2, using a sound-attenuated experimental apparatus, subjects could see, but not hear, male zebra finches and male Bengalese finches. The subjects did not show a significant preference for associating with zebra finches. In experiment 3, as in experiment 2, females could see live male zebra finches and male Bengalese finches in the sound-attenuated chambers. However, in experiment 3, the subjects also heard prerecorded auditory cues (i.e., songs and calls) of male zebra finches, which were presented simultaneously in both arms of the maze. Although the females could not use the auditory cues to identify the location of the male zebra finches, they preferred to associate with the male zebra finches rather than the male Bengalese finches. These results suggest that visual cues alone were effective in initiating choice behaviors by females and that auditory cues facilitate such visually based choice behaviors.

Why the better-than-average effect is a worse-than-average measure of self-enhancement: An investigation of conflicting findings from studies of East Asian self-evaluations

A recent meta-analysis on cross-cultural studies of self-enhancement finds that evidence for East Asian self-enhancement is consistently apparent only in studies where participants compare themselves to the average other, aka the “Better-than-Average” Effect (BAE). However, prior research has suggested that the BAE may conflate motivations to view the self in a positive light with non-motivational factors, such as a tendency to evaluate “everyone as better than average” [EBTA; Klar Y, Gilladi EE (1997) J Personal Soc Psychol 73:885–901]. In two studies, European-Canadian, Asian-Canadian, and Japanese students were asked to evaluate themselves as well as a fictitious student compared to the average. Replicating prior research, evidence for Japanese self-enhancement was found with the BAE, albeit weaker than Canadians. However, in the measures where the EBTA effect was circumvented, self-enhancement was no longer evident among Japanese. Likewise, within the BAE method, prior research has found that East Asians self-enhance more for important than unimportant traits. When the EBTA effect was circumvented this correlation was also significantly reduced. Findings from this research converge with other sources of evidence that East Asians do not appear to be motivated to self-enhance.

Working memory in spatial knowledge acquisition: Differences in encoding processes and sense of direction

This study examined how different components of working memory are involved in spatial knowledge acquisition for good and poor sense‐of‐direction (SOD) people. We employed a dual‐task method, and asked participants to learn routes from videos with verbal, visual and spatial interference tasks and without any interference. Results showed that participants with a good SOD encoded landmarks and routes verbally and spatially, and integrated knowledge about them into survey knowledge with the support of all three components of working memory. In contrast, participants with a poor SOD encoded landmarks only verbally, and tended to rely on the visual component of working memory in the processing of route knowledge. Based on the results, a possible model for explaining the differences in spatial knowledge acquisition and SOD was proposed. Copyright © 2010 John Wiley & Sons, Ltd.     

Individual differences in ego depletion: The role of sociotropy-autonomy

In his cognitive theory of depression, Beck (1987) suggested that highly sociotropic individuals have a strong need for social acceptance whereas highly autonomous individuals have an excessive need for achievement. Research by Baumeister (2000) has suggested that a phenomenon known as ego depletion, the weakening of performance on tasks following active self-control, occurs because it depletes a limited inner resource. The present study examined whether individuals who are highly sociotropic or autonomous would respond differently when faced with tasks requiring self-control. Participants completed the Sociotropy-Autonomy Scale (Clark et al. 1995) and engaged in two active self-control tasks. The results revealed that sociotropy levels were negatively correlated with persistence on tasks that require self-control whereas autonomy was positively correlated to persistence on the same task. In addition, the results suggested that, following a task requiring self-control, highly sociotropic individuals expend less effort, whereas highly autonomous individuals expend more effort on subsequent tasks requiring self-control.     

Mirrors in the head: cultural variation in objective self-awareness

In a society where there are pronounced concerns for "face," people come to be especially focused on how they are being evaluated by others. We reasoned that Japanese should conceive of themselves in terms of how they think they are considered by others. This hypothesis was tested by contrasting Japanese and North American participants who were in front of a mirror with those who were not. In two studies, replicating past research, North Americans who were in front of a mirror were more self-critical and were less likely to cheat than were those who were not in front of a mirror. In contrast, Japanese participants were unaffected by the presence of the mirror.     

Complexity and goodness of dot patterns varying in symmetry

Summary Two experiments were performed to specify stimulus determinants of pattern complexity and pattern goodness. Dot patterns distributed in 3×3 and 4×4 matrices with a rectilinear frame were used in Experiment 1, and dot patterns in hexagonal frameworks with a circular frame were used in Experiment 2. The patterns were invariant for transformations of rotation or reflection, and formed symmetry groups of different orders, i.e., cyclic and dihedral groups. The complexity and goodness of the patterns depended upon such stimulus variables as follows: (1) complexity decreased with the order of symmetry groups with equal weights for cyclic and dihedral groups, whereas goodness increased with the order of both symmetry groups with different weights; (2) the simplicity and goodness of patterns with a vertical axis were greater than those with a horizontal axis and those with an oblique one; (3) the complexity of the patterns that had collinear elements with equal length was rated the simplest; (4) pattern goodness increased as a function of the number of dots and the concentrations of dot to rotation/reflection axis in 3×3 and 4 × 4 matrices. Thus, complexity and goodness of pattern differed with respect to these stimulus variables.     

Effect of unpleasant loud noise on hippocampal activities during picture encoding: an fMRI study

The functional link between the amygdala and hippocampus in humans has not been well documented. We examined the effect of unpleasant loud noise on hippocampal and amygdaloid activities during picture encoding by means of fMRI, and on the correct response in humans. The noise reduced activity in the hippocampus during picture encoding, decreased the correct response and increased the activity of the amygdala. A path diagram using structural equation modeling suggested that hippocampus activity might be depressed by high amygdala activity. Therefore, noise should diminish memory by reducing hippocampal activity, which might be depressed by high amygdala activity.
