Psychosocial Factors Associated With Stage of Change for Contraceptive Use Among Women at Increased Risk for HIV and STDs

This study assessed the psychosocial factors associated with contraceptive use among inner-city women at risk for HIV/STDs by using the transtheoretical model of behavior change. The five-city study group of women aged 15 to 34 years was recruited from neighborhoods, social service agencies and shelters ( n = 998). We measured stages of change for contraceptive use and assessed theoretically proposed factors associated with being at a higher stage. Variables such as perceived advantages of contraceptive use and normative support for use were very important at early stages, but less important in later stages. However, self-efficacy was important in both early (OR =1.5) and later (OR = 1.6) stages, suggesting that women's confidence in their ability to initiate and sustain contraceptive use is crucial.     

Negative Intergroup Contact and Radical Right‐Wing Voting: The Moderating Roles of Personal and Collective Self‐Efficacy

This study examines whether negative contact with immigrants promotes voting for radical right‐wing parties, to what extent this relationship can be explained by feelings of outgroup threat, and whether this relationship depends on perceived personal and collective self‐efficacy. Hypotheses were tested among 630 native Dutch respondents, mainly living in multicultural neighborhoods. The results show that negative contact with immigrants is associated with feelings of personal (egocentric) and group (sociotropic) threat, and both these feelings, in turn, are associated with radical right‐wing voting. However, negative intergroup contact is less strongly related to egocentric threat when individuals feel able to personally address negative situations with other people (personal self‐efficacy). Furthermore, the findings suggest that negative intergroup contact is less strongly related to sociotropic threat when individuals believe that people in their neighborhood are able to collectively address some negative situations (collective self‐efficacy).     

The effects of repeated idea elaboration on unconscious plagiarism

Unconscious plagiarism occurs in a recall task when someone presents someone else’s idea as his or her own. Recent research has shown that the likelihood of such an error is inflated if the idea is improved during the retention interval, but not if it is imagined. Here, we explore the effects of repeating the elaboration phase during the retention interval. Participants in a group first generated alternate uses to common objects before elaborating the ideas either by imagining them or by improving them. This elaboration phase occurred once, twice, or not at all. Later, they attempted to recall their original ideas and generate new ideas. Repeated imagery did not inflate unconscious plagiarism on either task. In contrast, repeating the improvement phase increased plagiarism to dramatically high levels in the recall task. The latter effect might be particularly pertinent to real-world cases of plagiarism in which the ideas under dispute have been the subject of creative development over many occasions.     

Overcoming interference: an fMRI investigation of pattern separation in the medial temporal lobe

The medial temporal lobe (MTL) supports the formation and retrieval of long-term declarative memories, or memories for facts and everyday events. One challenge posed for this type of memory stems from the highly overlapping nature of common episodes. Within cognitive psychology, it is widely accepted that interference between information learned at different times is a major limitation on memory. In spite of several decades of intense research in the fields of interference theory and the neurobiological underpinnings of declarative memory, there is little direct evidence bearing on how the MTL resolves this interference to form accurate memories of everyday facts and events. Computational models of MTL function have proposed a mechanism in which the MTL, specifically the hippocampus, performs pattern separation, whereby overlapping representations are made less similar. However, there is little evidence bearing on how this process is carried out in the intact human MTL. Using high-resolution fMRI, we conducted a set of experiments that taxed behavioral pattern separation by using highly similar, interfering stimuli in a modified continuous recognition task. Regions within the parahippocampal gyrus demonstrated activity consistent with a "recall to reject" strategy. In contrast and critical to performing the task, activity within the hippocampus distinguished between correctly identified true stimulus repetitions, correctly rejected presentations of similar lure stimuli, and false alarms to similar lures. These data support the computational models' assertion that the hippocampus plays a key role in pattern separation.     

Children Expressing Mixed Emotion in a Nonsocial Context

Abstract

Efforts to demonstrate children’s ability to report experiencing mixed emotions have typically used an allocentric approach, asking children to report on emotions of other individuals in response to stories or movie clips demonstrating social themes. In contrast, literature examining children’s personal experiencing and understanding of their own mixed emotions, typified as an egocentric approach, in nonsocial situations remains underdeveloped. The current study examined the development of children’s reported understanding and experience of mixed emotions egocentrically. By examining a nonsocial context, this investigation extends existing gender- and age-related research on expressing egocentric mixed emotion. Using a computerized game with a disappointing wins paradigm, egocentric mixed emotional experience was elicited in 142 children (80 boys, 62 girls) aged 6 to 12?years. Results revealed that age, but not gender, was a statistically significant predictor of expressing egocentric mixed emotion experience and understanding. When studying mixed emotion development in a nonsocial context, gender did not contribute to differences in child reports. A significant positive relationship between egocentric mixed emotion experiencing and understanding also emerged. These findings contribute to our understanding of children’s emotion development and offer future directions for examining the broad domain of nonsocial contexts in youth expression of mixed emotions.     

Infant vocalization: A comprehensive view

Two different accounts of infant vocal development have recently been advanced. Both stress the lawful nature of this development and propose that it occurs in a series of stages. One account stresses the infant's attempt to make speech-like sounds from the earliest months and proposes that characteristics of speech are successively brought under the infant's control. The other suggests that instead, processes of integration and coordination of aspects of vocalization are taking place and considers these processes in relation to the situational contexts of vocalizing. A more comprehensive view is proposed in which aspects of both accounts are incorporated.     

The science of ethics: Deception, the resilient self, and the APA code of ethics, 1966-1973

This paper has two aims. The first is to shed light on a remarkable archival source, namely survey responses from thousands of American psychologists during the 1960s in which they described their contemporary research practices and discussed whether the practices were "ethical." The second aim is to examine the process through which the American Psychological Association (APA) used these survey responses to create principles on how psychologists should treat human subjects. The paper focuses on debates over whether "deception" research was acceptable. It documents how members of the committee that wrote the principles refereed what was, in fact, a disagreement between two contemporary research orientations. The paper argues that the ethics committee ultimately built the model of "the resilient self" into the APA's 1973 ethics code. At the broadest level, the paper explores how prevailing understandings of human nature are written into seemingly universal and timeless codes of ethics.
