De-Ontologizing the Debate on Social Explanations: A Pragmatic Approach Based on Epistemic Interests

In a recent paper on realism and pragmatism published in this journal, Osmo Kivinen and Tero Piiroinen have been pleading for more methodological work in the philosophy of the social sciences—refining the conceptual tools of social scientists—and less philosophically ontological theories. Following this de-ontologizing approach, we scrutinize the debates on social explanation and contribute to the development of a pragmatic social science methodology. Analyzing four classic debates concerning explanation in the social sciences, we propose to shift the debate away from (a) the ontologizing defenses of forms of social explanation, and (b) a winner-takes-all-approach. Instead, we advocate (c) a pragmatic approach towards social explanation, elaborating a rigorous framework for explanatory pluralism detached from the debates on social ontology.

Eyewitness recall: Regulation of grain size and the role of confidence

Eyewitness testimony plays a critical role in Western legal systems. Three experiments extended M. Goldsmith, A. Koriat, and A. Weinberg-Eliezer's (2002) framework of the regulation of grain size (precision vs. coarseness) of memory reports to eyewitness memory. In 2 experiments, the grain size of responses had a large impact on memory accuracy. Further, participants achieved a compromise between the accuracy and informativeness of their testimony by volunteering precise answers only when likely to be correct. The level of detail reported was strongly, positively related to confidence in the accuracy of the response. This highlights the importance of considering the level of detail, not just the accuracy, of eyewitness testimony.     

Examining career-related mentoring and managerial performance across cultures: A multilevel analysis

The benefits of the mentoring relationship for protégés have been a primary focus in the mentoring literature. Researchers have recently begun to examine how mentoring can benefit the mentor. The purpose of the present study is to examine whether direct report-ratings of a manager’s career-related mentoring behaviors are related to boss-ratings of that manager’s performance. In addition, this study assesses whether the cultural background of the manager moderates the career-related mentoring-performance relationship via multilevel methodology. Results reveal that managers who are rated by their direct reports as engaging in career-related mentoring behaviors are perceived as better performers by their bosses. Moreover, the GLOBE societal culture dimension of Performance Orientation was a significant cross-level moderator of the career-related mentoring-performance relationship. Implications for the practice of mentoring in cross-cultural contexts across multiple disciplines are discussed.     

Hemispheric specialization for language according to grapho-phonemic transformation and gender. A divided visual field experiment

This behavioral study aimed at assessing the effect of two variables on the degree of hemispheric specialization for language. One of them was the grapho-phonemic translation (transformation) (letter-sound mapping) and the other was the participants’ gender. The experiment was conducted with healthy volunteers. A divided visual field procedure has been used to perform a phoneme detection task implying either regular (transparent) grapho-phonemic translation (letter-sound mapping consistency) or irregular (non-transparent) grapho-phonemic translation (letter-sound mapping inconsistency). Our results reveal a significant effect of grapho-phonemic translation on the degree of hemispheric dominance for language. The phoneme detection on items with transparent translation (TT) was performed faster than phoneme detection on items with non-transparent translation (NTT). This effect seems to be due to faster identification of TT than NTT when the items were presented in the left visual field (LVF)-right hemisphere (RH). There was no difference between TT and NTT for stimuli presented in the right visual field (RVF)-left hemisphere (LH). This result suggests that grapho-phonemic translation or the degree of transparency can affect the degree of hemispheric specialization, by modulating the right hemisphere activity. With respect to gender, male participants were significantly more lateralized than female participants but no interaction was observed between gender and degree of transparency.     

Gendered Ways to Motivation Gains in Groups

Recent studies have demonstrated motivation gains of low performing group members even beyond the level of an individual work baseline (e.g., Weber and Hertel, Journal of Personality and Social Psychology, 93:973–993, 2007). We expected that the underlying mechanisms of these motivation gains, i.e., social indispensability and social competition, are moderated by individuals’ gender. Moreover, these gender effects were assumed to be moderated by partner anonymity. Predictions were tested with mostly undergraduate German students (N?=?213) working in same-gender groups in a computer-supported environment. Results revealed that motivation gains due to social indispensability were more likely for women, whereas motivation gains due to social competition were more likely for men. Furthermore, women compared to men showed higher motivation gains in anonymous conditions compared to conditions with an acquainted partner.     

Risk as feelings

Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to arrive at a decision. The authors propose an alternative theoretical perspective, the risk-as-feelings hypothesis, that highlights the role of affect experienced at the moment of decision making. Drawing on research from clinical, physiological, and other subfields of psychology, they show that emotional reactions to risky situations often diverge from cognitive assessments of those risks. When such divergence occurs, emotional reactions often drive behavior. The risk-as-feelings hypothesis is shown to explain a wide range of phenomena that have resisted interpretation in cognitive-consequentialist terms.     

The role of prosody in the interpretation of structural ambiguities: a study of anticipatory eye movements

An eye-tracking experiment examined whether prosodic cues can affect the interpretation of grammatical functions in the absence of clear morphological information. German listeners were presented with scenes depicting three potential referents while hearing temporarily ambiguous SVO and OVS sentences. While case marking on the first noun phrase (NP) was ambiguous, clear case marking on the second NP disambiguated sentences towards SVO or OVS. Listeners interpreted case-ambiguous NP1s more often as Subject, and thus expected an Object as upcoming argument, only when sentence beginnings carried an SVO-type intonation. This was revealed by more anticipatory eye movements to suitable Patients (Objects) than Agents (Subjects) in the visual scenes. No such preference was found when sentence beginnings had an OVS-type intonation. Prosodic cues were integrated rapidly enough to affect listeners' interpretation of grammatical function before disambiguating case information was available. We conclude that in addition to manipulating attachment ambiguities, prosody can influence the interpretation of constituent order ambiguities.     

Metachromatic Leukodystrophy and Nonverbal Learning Disability: Neuropsychological and Neuroradiological Findings in Heterozygous Carriers

Metachromatic leukodystrophy (MLD) is an autosomal recessive neurodegenerative disorder due to deficiency of the enzyme arylsulfatase A that leads to progressive, diffuse demyelination. The syndrome of nonverbal learning disability has been attributed to white matter abnormality and has been reported in children with this disorder and in some healthy family member carriers of gene. We examined the neuropsychologic profiles and MRIs of eight members of the family of a 7-year-old girl with this disease, all of whom were heterozygous carriers of the mutation and five of whom were also carriers of the MLD pseudodeficiency gene. All had low normal levels of arylsulfatase A, and seven of the eight had average or better profiles across all assessed neuropsychological domains. The patient's younger sister had a profile with features of the syndrome of nonverbal learning disability despite a normal MRI, whereas two members with minor white matter findings did not. This family does not provide evidence for the syndrome of nonverbal learning disability in heterozygous carriers of the gene for MLD, even when associated with the MLD pseudodeficiency gene.     

A mere exposure effect for transformed three-dimensional objects: Effects of reflection, size, or color changes on affect and recognition

If the mere exposure effect is based on implicit memory, recognition and affect judgments should be dissociated by experimental variables in the same manner as other explicit and implicit measures. Consistent with results from recognition and picture naming or object decision priming tasks (e.g., Biederman & E. E. Cooper, 1991, 1992; L. A. Cooper, Schacter, Ballesteros, & Moore, 1992), the present research showed that recognition memory but not affective preference was impaired by reflection or size transformations of three-dimensional objects between study and test. Stimulus color transformations had no effect on either measure. These results indicate that representations that support recognition memory code spatial information about an object’s left-right orientation and size, whereas representations that underlie affective preference do not. Insensitivity to surface feature changes that do not alter object form appears to be a general characteristic of implicit memory measures, including the affective preference task.
