Psychology,population, and reproductive behavior

This special section on international perspectives in psychology focuses on population issues and reproductive behavior across national and cultural boundaries, emphasizing the responsibility of psychologists and colleagues in related disciplines to generate and communicate culturally mindful findings likely to shape public health policy and improve human well-being. After considering the historical and policy context, it highlights internationally collaborative research projects in the Czech Republic, Egypt, Mexico, and the United States that address reproductive behavior, women's roles and status, responsible parenthood, and abortion legislation in terms of cultural context, gender equity, the needs of adolescents, and public health policy. The articles illustrate the importance of the cultural context within which psychological research is conducted and how psychology can be informed by international perspectives.     

The developmental ecology of urban males' youth violence

Data from a longitudinal study of 294 African American and Latino adolescent boys and their caregivers living in poor urban communities were used to test a developmental-ecological model of violence. Six annual waves of data were applied to evaluate the relations between microsystem influences of parenting and peer deviance (peer violence and gang membership), macrosystem influences of community structural characteristics and neighborhood social organization, and individual involvement in violence (level and growth). Structural equation modeling analyses showed that community structural characteristics significantly predicted neighborhood social processes. Parenting practices partially mediated the relation between neighborhood social processes and gang membership. Parenting practices was fully mediated in its relation to peer violence by gang membership. Gang membership was partially mediated by peer violence level in its relation to individual violence level. Although the overall set of relations does not satisfy mediation requirements fully in all instances, the model was validated for the most part, supporting a focus on a multilevel ecological model of influences on risk development.     

What is "marked" in visual marking? Evidence for effects of configuration in preview search

Visual search for a conjunction target is facilitated when distractor sets are segmented over time: the preview benefit Watson and Humphreys (1997) suggested that this benefit involved inhibition of old items (visual marking, VM). We investigated whether the preview benefit is sensitive to the configuration of the old distractors. Old distractors changed their location prior to the occurrence of the new items, while also either changing or maintaining their configuration. Configuration changes disrupted search. The results are consistent with object-based VM, which is sensitive to the configuration of old stimuli.     

What you get out of memory depends on the question you ask

Following study, participants received 2 tests. The 1st was a recognition test; the 2nd was designed to tap recollection. The objective was to examine performance on Test 1 conditional on Test 2 performance. In Experiment 1, contrary to process dissociation assumptions, exclusion errors better predicted subsequent recollection than did inclusion errors. In Experiments 2 and 3, with alternate questions posed on Test 2, words having high estimates of recollection with one question had high estimates of familiarity with the other question. Results supported the following: (a) the 2-test procedure has considerable potential for elucidating the relationship between recollection and familiarity; (b) there is substantial evidence for dependency between such processes when estimates are obtained using the process dissociation and remember-know procedures; and (c) order of information access appears to depend on the question posed to the memory system.     

Disproportionate deficit in associative recognition relative to item recognition in global amnesia

In two experiments, we tested the hypothesis that medial temporal lobe (MTL) amnesic patients and, likewise, diencephalic (DNC) amnesic patients evidence a disproportionate deficit in memory for associations in comparison with memory for single items. In Experiment 1, we equated item recognition in amnesic and control participants and found that, under these conditions, associative recognition remained impaired both for MTL patients and for DNC patients. To rule out an alternative interpretation of the results of Experiment 1, in Experiment 2 we compared the performance of amnesic and control participants on a one-item recognition task and a two-item recognition task that required no memory for the association between members of word pairs. In the MTL group, when single-item recognition was equated to that of the controls, two-item nonassociative pair memory was equivalent as well. In the DNC group, nonassociative pair memory was impaired, but this impairment did not fully account for the impairment in associative memory. These findings indicate that memory for novel associations between items is disproportionately impaired in comparison with memory for single items in amnesia.     

Incidental learning of real-world regularities

The large literature on incidental learning relies almost exclusively on laboratory experiments. Whenever researchers have attempted to demonstrate incidental learning of real-world regularities, they have typically failed to show learning. For example, it is well established that people do not learn regularities in everyday objects, such as the left-right orientation of faces on coins, despite a very large exposure to them. In this report, we examine this apparent contradiction. We argue that most studies exploring real-life incidental learning use tests that are not as sensitive to low-confidence information as those traditionally used in laboratory tasks. Using more sensitive measures, we show that it is possible to learn regularities from British and Japanese cultural life as a direct result of exposure to these regularities. Further, confidence measures suggest that although the information may be acquired incidentally, it can be expressed with and without concomitant awareness of that knowledge.     

Asymmetric dependencies in perceiving identity and emotion: experiments with morphed faces.

We investigated whether an asymmetric relationship between the perception of identity and emotional expressions in faces (Schweinberger & Soukup, 1998) may be related to differences in the relative processing speed of identity and expression information. Stimulus faces were morphed across identity within a given emotional expression, or were morphed across emotion within a given identity. In Experiment 1, consistent classifications of these images were demonstrated across a wide range of morphing, with only a relatively narrow category boundary. At the same time, classification reaction times (RTs) reflected the increased perceptual difficulty of the morphed images. In Experiment 2, we investigated the effects of variations in the irrelevant dimension on judgments of faces with respect to a relevant dimension, using a Garner-type speeded classification task. RTs for expression classifications were strongly influenced by irrelevant identity information. In contrast, RTs for identity classifications were unaffected by irrelevant expression information, and this held even for stimuli in which identity was more difficult and slower to discriminate than expression. This suggests that differences in processing speed cannot account for the asymmetric relationship between identity and emotion perception. Theoretical accounts proposing independence of identity and emotion perception are discussed in the light of these findings.     

Can Bartlett’s repeated reproduction experiments be replicated?

Surprisingly, Bartlett's (1932) famous repeated reproduction experiments, in which he found systematically increasing errors in recall from the same people tested over time, have never been successfully replicated. Several studies have attempted partial replications, which were unsuccessful, and their authors concluded that the original observations might not be replicable. We conducted a study modeled closely after Bartlett's procedures: Subjects studied "The War of the Ghosts," took an initial test 15 min later, and then took a delayed test after 1 week. A follow-up test was conducted 6 months later on as many subjects as could be obtained. We did replicate Bartlett's results, in that (1) subjects forgot the story over delays but (2) introduced rationalization and distortion into their accounts of the story, with increases in the proportion of material distorted as retention interval increased. Subjects also imported new propositions at long delays, further confirming Bartlett's empirical observations and conclusions. Bartlett's repeated reproduction results can be replicated.     

The Interactive Role of Negative Affectivity and Job Characteristics: Are High-NA Employees Destined to Be Unhappy at Work?1

The present study examined whether employees high in negative affectivity (NA) are destined to be unhappy at work. Managerial employees provided information regarding perceptions of job characteristics, negative affectivity (NA), job satisfaction, and intentions to turnover. Using hierarchical regression, our findings suggest that employees who reported being high NA were more reactive to the environmental cues of perceived job scope. Specifically, NA interacted with job scope such that individuals high in NA who perceived their jobs as being higher (lower) in scope reported more (less) job satisfaction than did individuals low in NA. Implications for organizations and future research directions are discussed.
