Do infants possess innate knowledge structures? The con side

The central question of development is how new forms are made, how some structure, or behavior, or competence that was not there before, arises. This essay argues for a mechanistic answer to the question of the origins of new forms. And, in so doing, the essay argues that the so-called ‘innate versus learned’ dichotomy is logically flawed since ‘innate’ has no specifiable and mechanistic meaning. The essay considers first, a clear case of ‘innate’ structure: the origins of fingers and toes in embryology. The real-time mechanisms which create fingers and toes, however, are general, probabilistic, emergent and distributed across several levels of analyses. The idea of ‘innate’– even though certainly applicable – has no substantive content and yields no predictions about the nature of these mechanisms. The essay considers second, a clear case of a ‘learned’ structure: the origins of the shape bias in children’s early noun learning. Again, the developmental mechanisms are general, probabilistic, emergent and distributed across several levels of analyses. Several criticisms of the argument against ‘innate ideas’ are considered and rebutted.     

Natural Theology in Paul? Reading Romans 1.19–20

This reading of Romans 1.19–20 suggests that, viewed within the argumentative progression of the letter from 1.18–3.20, these verses are properly understood as a subversion of the premises of natural revelation, rather than an endorsement of them. The traditional account of Paul's argument, in which 1.19–20 announces a theology of natural knowledge of God, is contradicted both by Paul's wider theological commitments and by his attitude to the privileges of Judaism. An alternative construal of the argument considers it as an ad hominem strategy, in which the opening verses serve to recapitulate at the beginning of the argument the presuppositions that Paul seeks ultimately to overthrow.     

A computerized slot machine simulation to investigate the variables involved in gambling behavior

The present paper describes a computerized slot machine simulation designed to examine many of the potential variables involved in gambling behavior. This program was created in Visual Basic Version 6.0 and is designed to run on any Windows 95 or higher equipped computer. The program allows for experimenter manipulation of probabilities of payoffs, visual display of potential winning symbols, exact sequences of wins and losses, as well as pose run time questions to the subject on prespecified trials. The program records data on a trial-bytrial basis to a text file for easy importation into many data analysis and statistical programs. Conceptual and experimental questions that may be addressed with the described program are also discussed.     

Division by multiplication

In two experiments, item-specific transfer was examined in simple multiplication and division with prime and probe problems separated by four to six trials. As was predicted by Rickard and Bourne's (1996) identical-elements model, response time (RT) savings were larger with identical (e.g., prime 63 divided by 7, probe 63 divided by 7) than with inverted (63 divided by 9 and 63 divided by 7) division problems, whereas identical (7 x 9 and 7 x 9) and inverted (9 x 7 and 7 x 9) multiplication problems produced equivalent transfer. Nonetheless, there was statistically significant transfer between inverted division problems. Furthermore, RT savings in the multiplication-to-division transfer conditions (e.g., prime 7 x 9, probe 63 divided by 7) indicated that multiplication mediated large-number division problems. These latter effects are not predicted by the identical-elements model but may be reconciled with the model by distinguishing associative transfer (facilitation owing to strengthening of a common problem node in memory) from mediated transfer (facilitation owing to mediation by a strengthened, related problem). Skilled adults can exploit the conceptual correspondences between multiplication and division facts in a highly efficient way to facilitate performance.     

More about brows: how poses that change brow position affect perceptions of gender

The speeded categorisation of gender from photographs of men's and women's faces under conditions of vertical brow and vertical head movement was explored in two sets of experiments. These studies were guided by the suggestion that a simple cue to gender in faces, the vertical distance between the eyelid and brow, could support such decisions. In men this distance is smaller than in women, and can be further reduced by lowering the brows and also by lowering the head and raising the eyes to camera. How does the gender-classification mechanism take changes in pose into account? Male faces with lowered brows (experiment 1) were more quickly and accurately categorised (there was little corresponding 'feminisation' of raised-brow faces). Lowering gaze had a similar effect, but failed to interact with head lowering in a simple manner (experiment 2). We conclude that the initial classification of gender from the facial image may not involve normalisation of the face image to a canonical state (the 'mug-shot view') for expressive pose (brow movement and direction of gaze). For head pose (relative position of the features when the face is not viewed head-on), normalisation cannot be ruled out. Some perceptual mechanisms for these effects, and their functional implications, are discussed.     

Data versus Spock: lay theories about whether emotion helps or hinders

The android Data from Star Trek admired human emotion whereas Spock viewed emotion as irrational and maladaptive. The theory that emotions fulfil adaptive functions is widely accepted in academic psychology but little is known about laypeople’s theories. The present study assessed the extent to which laypeople share Data’s view of emotion as helpful or Spock’s view of emotion as a hindrance. We also assessed how help and hinder theory endorsement were related to reasoning, emotion regulation, and well-being. Undergraduates (N?=?630) completed a stressful timed reasoning task and questionnaires that assessed their theories of emotion, emotion regulation strategies, happiness, and social support. Overall, participants viewed emotion more as a help than a hindrance. The more they endorsed the view that emotion helps, the better their reasoning scores. Endorsing a help theory also predicted the use of reappraisal which, in turn, predicted greater happiness and social support. In contrast, endorsing the view that emotion hinders was associated with emotion suppression and less social support. Thus, people’s theories about the functionality of emotion may have important implications for their reasoning and emotional well-being.     

Controlling for Prior Attainment Reduces the Positive Influence that Single-Gender Classroom Initiatives Exert on High School Students’ Scholastic Achievements

Research points to the positive impact that gender-segregated schooling and classroom initiatives exert on academic attainment. An evaluation of these studies which reveal positive effects highlights, however, that students are typically selectively assigned to single- or mixed-gender instructional settings, presenting a methodological confound. The current study controls for students’ prior attainment to appraise the efficacy of a single-gender classroom initiative implemented in a co-educational high school in the United Kingdom. Secondary data analysis (using archived data) was performed on 266 middle-ability, 11–12 year-old students’ standardized test scores in Languages (English, foreign language), STEM-related (Mathematics, Science, Information and Communication Technology), and Non-STEM subjects (art, music, drama). Ninety-eight students (54, 55% female) were taught in single-gender and 168 (69, 41% female) in mixed-gender classrooms. Students undertook identical tests irrespective of classroom type, which were graded in accordance with U.K national curriculum guidelines. Controlling for students’ prior attainment, findings indicate that students do not appear to benefit from being taught in single-gender relative to mixed-gender classrooms in Language and STEM-related subjects. Young women benefitted from being taught in mixed-gender relative to single-gender classes for Non-STEM subjects. However, when prior ability is not controlled for, the intervention appears to be effective for all school subjects, highlighting the confounding influence of selective admissions. These findings suggest that gender-segregated classroom initiatives may not bolster students’ grades. It is argued that studies that do not control for selection effects may tell us little about the effectiveness of such interventions on scholastic achievement.     

Distress in spouses of Vietnam veterans: associations with communication about deployment experiences

Emerging literature shows a consistent pattern of relationship and psychological distress in spouses or partners of combat veterans with symptoms of posttraumatic stress disorder (PTSD). One possible mechanism of partners' distress posited in clinical literature is that excessive discussion of traumatic events from deployment may have negative effects on partners. At the extreme, some partners are suggested to develop PTSD-like symptoms, or secondary traumatic stress. Despite these hypotheses, there have been few empirical tests of the effects of communicating about such events. In a sample of 465 combat veterans and their spouses who participated in the Family Interview Component of the National Vietnam Veterans Readjustment Study, we explored how the extent of couples' deployment-related communication was associated with partner relationships and psychological distress, and whether such associations were moderated by the severity of veterans' PTSD symptoms. Results showed that Vietnam-specific communication correlated negatively with relationship distress, but the effect was negligible after controlling for overall communication in the relationship. On the other hand, Vietnam-specific communication did not correlate with psychological distress, but the association was significantly moderated by veterans' PTSD symptom severity. Specifically, communication about Vietnam was increasingly and positively associated with partners' psychological distress as veterans' symptoms of PTSD rose into the clinical range, but nonsignificantly and negatively associated with such distress as PTSD symptoms decreased below this level. The findings support previous clinical recommendations that couples' discussions of potentially traumatic events be approached cautiously, and they suggest a need to attend to the content of couples' communications when conducting dyadic interventions for PTSD.     

Advancing Organizational Support Theory into the Twenty-First Century World of Work

Purpose

This review focuses and aids the development of organizational support theory, which explains relationships between employers and employees based on social exchange. Many studies have explored the theory??s central construct, perceived organizational support (POS), or the degree to which employees believe their work organization values their contributions and cares about their well-being. Since the last review of POS literature in 2000, the occupational landscape has shifted, increasing nontraditional work relationships and the importance of managing an international workforce while considering influences on employee well-being. This review discusses how the recent POS research reflects these trends.

Design/Methodology/Approach

This review focused on how themes in the POS research since 2000 have enhanced organizational support theory as relevant to the twenty-first century world of work.

Findings

Four important theoretical themes have developed since 2000 that enhance organizational support theory: considerations of employee well-being, nontraditional workers, international and cross-cultural issues, and developments tied to the use of multilevel modeling.

Implications

Giving both researchers and practitioners a synthesized view of the current status of POS research, this review serves as a springboard for new developments. It also integrates the multitude of recent studies into organizational support theory, focusing theoretical progress.

Originality/Value

This is the first review and theoretical integration of the POS literature since 2002. It is a valuable resource for all interested in the field, with theoretical insights, useful tables, explanatory figures, and references.
