The impact of self‐confidence on the compromise effect

This research reports an investigation into whether the personality aspect of self‐confidence affects the compromise effect. We hypothesize that highly self‐confident people have greater certainty in making decisions and are more attracted to risk‐taking, which makes them less likely to choose the safe or middle option in a large choice set. The three studies involved are conducted using between‐ and within‐subjects experimental designs. Various product categories are used to generalize the findings. Study 1 looks at purchasing decisions and utilizes three scales of self‐confidence, risk preference, and uncertainty; it demonstrates that consumers with high self‐confidence are less likely to choose a compromise option due to high certainty in their decision‐making. Study 2 discovers that people with low self‐confidence are more likely to choose the middle option in a risky condition than in a nonrisky condition. Study 3 decomposes self‐confidence into general and specific self‐confidence, and reveals that people with low general self‐confidence and low specific self‐confidence are more likely to choose the middle option.     

Developmental trajectory of neural specialization for letter and number visual processing

Adult neuroimaging studies have demonstrated dissociable neural activation patterns in the visual cortex in response to letters (Latin alphabet) and numbers (Arabic numerals), which suggest a strong experiential influence of reading and mathematics on the human visual system. Here, developmental trajectories in the event‐related potential (ERP) patterns evoked by visual processing of letters, numbers, and false fonts were examined in four different age groups (7‐, 10‐, 15‐year‐olds, and young adults). The 15‐year‐olds and adults showed greater neural sensitivity to letters over numbers in the left visual cortex and the reverse pattern in the right visual cortex, extending previous findings in adults to teenagers. In marked contrast, 7‐ and 10‐year‐olds did not show this dissociable neural pattern. Furthermore, the contrast of familiar stimuli (letters or numbers) versus unfamiliar ones (false fonts) showed stark ERP differences between the younger (7‐ and 10‐year‐olds) and the older (15‐year‐olds and adults) participants. These results suggest that both coarse (familiar versus unfamiliar) and fine (letters versus numbers) tuning for letters and numbers continue throughout childhood and early adolescence, demonstrating a profound impact of uniquely human cultural inventions on visual cognition and its development.     

Gender Differences in Psychological Distress Among Immigrants from the Former Soviet Union

In this study we compared rates and correlates of psychological distress among immigrant women and men from the former Soviet Union. A demographic, migration, and social network questionnaire and the Symptom Checklist-90-R were administered to 935 female and 706 male immigrants. Older age and less time in the United States predicted distress in both gender groups. However, having less education, leaving relatives behind, and not being sponsored by friends or a religious organization predicted greater distress for women. Women reported significantly more distress than men except for those men who were married and retired.     

Coping attitudes, sources, and practices among Black and Latino college students

We investigated 130 Black and Latino college students regarding their concerns, attitudes toward professional counseling, sources of support, and coping activities. We found that the Black and Latino cultural emphasis on interdependence influenced attitudes toward using professional resources such as a counselor. We also found a significant two-way interaction between gender and race for attitudes toward professional counseling: Black males had less favorable attitudes in comparison to Black females, while Latino males had more favorable attitudes than did Latino females. Both Black and Latino college students had favorable attitudes toward informal support networks. Differences between Black and Latino college students were found for reported concerns and coping sources. Implications for counseling theory, practice, and research are discussed.     

Effecting science, affecting medicine: homosexuality, the Kinsey reports, and the contested boundaries of psychopathology in the United States, 1948-1965

Despite the well-documented intensive battle between Alfred Kinsey and American psychiatrists around the mid-twentieth century, this paper argues that Kinsey's work, in fact, played a significant role in transforming mental health experts' view of homosexuality starting as far back as the late 1940s and extending all the way through the mid-1960s. After analyzing the way in which Kinsey's work pushed American psychiatrists to re-evaluate their understanding of homosexuality indirectly through the effort of clinical psychologists, I then focus to a greater extent on examples that illustrate how the Kinsey reports directly influenced members of the psychiatric community. In the conclusion, using a Foucauldian conception of "discourse," I propose that in order to approach the struggle around the pathological status of homosexuality in the 1950s and the 1960s, thinking in terms of a "politics of knowledge" is more promising than simply in terms of a "politics of diagnosis." Central to the struggle was not merely the matter of medical diagnosis, but larger issues regarding the production of knowledge at an intersection of science and medicine where the parameters of psychopathology were disputed in the context of mid-twentieth-century United States.     

Activation of amygdaloid PKC pathway is necessary for conditioned cues-provoked cocaine memory performance

Drug-associated cues are critical in reinstating the drug taking behavior even during prolonged abstinence and thus are thought to be a key factor to induce drug craving and to cause relapse. Amygdaloid complex has been known for its physiological function in mediating emotional experience storage and emotional cues-regulated memory retrieval. This study was undertaken to examine the role of basolateral nuclei of amygdala and the intracellular signaling molecule in drug cues-elicited cocaine memory retrieval. Systemic anisomycin treatment prior to the retrieval test abolished the cues-provoked cocaine conditioned place preference (CPP) memory. Likewise, a similar blockade of cues-provoked cocaine CPP performance was achieved by infusion of anisomycin and cycloheximide into the basolateral nuclei of amygdala before the test. Intra-amygdaloid infusion of H89, a protein kinase A inhibitor, or U0126, a MEK inhibitor, did not affect retrieval of the cues-elicited cocaine CPP memory. In contrast, intra-amygdaloid infusion of NPC 15437, a PKC inhibitor, abolished the cues-elicited cocaine CPP expression, while left the memory per se intact. Intra-amygdaloid infusion of NPC 15437 did not seem to affect locomotor activity or exert observable aversive effect. Taken together, our results suggest that activation of PKC signaling pathway and probably downstream de novo protein synthesis in the basolateral nuclei of amygdala is required for the cues-elicited cocaine memory performance. However, temporary inhibition of this signaling pathway does not seem to affect cocaine CPP memory per se.     

Learning geographical information from hypothetical maps

People show biases or distortions in their geographical judgments, such as mistakenly judging Rome to be south of Chicago (the Chicago-Rome illusion). These errors may derive from either perceptual heuristics or categorical organization. However, previous work on geographic knowledge has generally examined people's judgments of real-world locations for which learning history is unknown. This article reports experiments on the learning of hypothetical geographical spaces, in which participants acquired information in a fashion designed to control real-world factors, such as variable travel experiences or stereotypes about other countries, as well as to mimic initial encounters with locations through reading or conventional school-based geography education. Five experiments combine to suggest that biases in judgment based on learning of this kind are different in key regards from those seen with real-world geography and may be based more on the use of perceptual heuristics than on categorical organization.     

Individual differences and interrelationships among a select set of cognitive skills

An experiment was conducted to investigate individual differences and interrelationships in performance on three short-term memory processing and visual processing tasks. Parameters of models for these tasks were correlated. High correlations (.97 and .83) were obtained for some intertask parameters. indicating that elemental component processes for different tasks can be identified that are similar or highly related. Psychometric measures (SATM and SATV) were also correlated with the information processing model parameters. High multiple correlations of SATV and SATM were obtained using model parameters as predictors. when the data were analyzed separately for female and male subjects. The results are suggestive of sex differences in the interrelationships of the cognitive processes under investigation.     

Benefits of Incubation on Divergent Thinking

Studies on whether fixation cues provided in the first episode of divergent thinking tasks influence creative outcomes after incubation, as they do for convergent problem-solving tasks, remain limited. This research examined the beneficial effects of incubation using the delayed- and immediate-incubation paradigms. Participants in Experiment 1 were either provided or not provided fixation cues during the first episode of a new type of divergent-thinking task, similar to creating titles in plot stories. The results indicated that fixation cues moderated people’s creative outcomes after incubation. Going through incubation did not improve the participants’ creativity in the second episode for strong fixation cues. By contrast, an incubation period led to the generation of more divergent items in the second episode compared to the first episode for less strong fixation cues, and this led to the performance matching the condition without fixation cues. The results from Experiment 2 suggested that immediate incubation downsized the influence of fixation cues. Therefore, if people want to promote their creativity through a period of incubation, the outcomes may still depend on the conditions of environments in which the creative works are executed.     

The emotional integration of childhood experience: physiological, facial expressive, and self-reported emotional response during the adult attachment interview

Attachment researchers claim that individual differences in how adults talk about their early memories reflect qualitatively distinct organizations of emotion regarding childhood experiences with caregivers. Testing this assumption, the present study examined the relationship between attachment dimensions and physiological, facial expressive, as well as self-reported emotional responses during the Adult Attachment Interview (AAI). Consistent with theoretical predictions, more prototypically secure adults behaviorally expressed and reported experiencing emotion consistent with the valence of the childhood events they described. Insecure adults also showed distinctive and theoretically anticipated forms of emotional response: Dismissing participants evidenced increased electrodermal activity during the interview, a sign of emotional suppression, whereas preoccupied adults showed reliable discrepancies between the valence of their inferred childhood experiences and their facial expressive as well as reported emotion during the AAI. Results substantiate a case that the AAI reflects individual differences in emotion regulation that conceptually parallel observations of attachment relationships in infancy.
