ACCULTURATION INDICES AS A MEANS OF CONFIRMING CULTURAL DIFFERENCES

The acculturation of subjects from culture A to culture B can take three forms: the more acculturated subjects may make responses that are similar to the responses made by subjects from culture B (accommodation), they may go beyond B's position (overshooting), and they may move in the opposite direction from the position of the members of culture B (ethnic affirmation). The paper presents three sets of data concerning elements of subjective culture (role perceptions, behavioral intentions, and stereotypes), with subjects speaking Spanish and residing in the U.S. who are at three levels of acculturation. The data show that role perceptions and behavioral intentions are characterized mostly by accommodation, while stereotypes are characterized mostly by ethnic affirmation. A theoretical explanation of this pattern of results is that elements of subjective culture are linked to overt behavior both directly and indirectly. As members of culture A acculturate to culture B, their behavior becomes similar to the behavior of members of culture B. Those elements of subjective culture that are directly linked with this behavior change; however, those elements that are not directly linked do not change or even show ethnic affirmation. Testing of this theoretical formulation will require additional research. L'acculturation de sujets d'une culture A à une culture B peut prendre trois formes: Les sujets les plus acculturés peuvent donner des réponses qui sont semblables aux réponses données par des sujets de la culture B (accommodation), ils peuvent aller au-delà de la position de la culture B (surpassement) et ils peuvent aller dans une direction opposée de celle des membres de la culture B (affirmation ethnique). Cet article présente trois groupes de données qui concernent des éléments de culture subjective (perception des rôles, intentions comportementales et stéréotypes), avec des sujets hispanophones résidant aux Etats-Unis et des trois niveaux d'acculturation. Les données montrent que les perceptions de rôle et les intentions comportementales sont caractérisées surtout par l'accommodation tandis que les stéréotypes sont caractérisées surtout par l'affirmation ethnique. Une explication possible de ces résultats est que des éléments de culture subjective sont liés directement et indirectement au comportement ouvert. Le comportement de membres d'une culture A acculturés à une culture B devient similaire au comportement des membres de cette culture B. Les éléments de culture subjective qui sont directement liés à ce comportement changent; cependant les éléments qui ne lui sont pas liés restent inchangés ou présentent měme une affirmation ethnique. Des recherches supplémentaires seront nécessaires pour tester cette formulation théorique.     

Cross-modal interactions in the perception of musical performance

We investigate the dynamics of sensory integration for perceiving musical performance, a complex natural behavior. Thirty musically trained participants saw, heard, or both saw and heard, performances by two clarinetists. All participants used a sliding potentiometer to make continuous judgments of tension (a measure correlated with emotional response) and continuous judgments of phrasing (a measure correlated with perceived musical structure) as performances were presented. The data analysis sought to reveal relations between the sensory modalities (vision and audition) and to quantify the effect of seeing the performances on participants' overall subjective experience of the music. In addition to traditional statistics, functional data analysis techniques were employed to analyze time-varying aspects of the data. The auditory and visual channels were found to convey similar experiences of phrasing but different experiences of tension through much of the performances. We found that visual information served both to augment and to reduce the experience of tension at different points in the musical piece (as revealed by functional linear modeling and functional significance testing). In addition, the musicians' movements served to extend the sense of phrasing, to cue the beginning of new phrases, to indicate musical interpretation, and to anticipate changes in emotional content. Evidence for an interaction effect suggests that there may exist an emergent quality when musical performances are both seen and heard. The investigation augments knowledge of human communicative processes spanning language and music, and involving multiple modalities of emotion and information transfer.     

Transgenic mice expressing a truncated form of CREB-binding protein (CBP) exhibit deficits in hippocampal synaptic plasticity and memory storage

Deletions, translocations, or point mutations in the CREB-binding protein (CBP) gene have been associated with Rubinstein-Taybi Syndrome; a human developmental disorder characterized by retarded growth and reduced mental function. To examine the role of CBP in memory, transgenic mice were generated in which the CaMKII alpha promoter drives expression of an inhibitory truncated CBP protein in forebrain neurons. Examination of hippocampal long-term potentiation (LTP), a form of synaptic plasticity thought to underlie memory storage, revealed significantly reduced late-phase LTP induced by dopamine-regulated potentiation in hippocampal slices from CBP transgenic mice. However, four-train induced late-phase LTP is normal. Behaviorally, CBP transgenic mice exhibited memory deficits in spatial learning in the Morris water maze and deficits in long-term memory for contextual fear conditioning, two hippocampus-dependent tasks. Together, these results demonstrate that CBP is involved in specific forms of hippocampal synaptic plasticity and hippocampus-dependent long-term memory formation.     

“Hello,can you hear me?”: Narratives of online mental health counselling among Filipino adults during the pandemic

Filipinos are often reluctant to seek professional mental health (MH) help. However, literature reveals that online counselling is preferable to face-to-face (F2F) MH services, with the pandemic possibly magnifying technology's anonymity and disinhibiting benefits. To further explore facilitators of online MH help-seeking, this study tapped into the lived stories of Filipino adults who experienced at least one counselling session from March 2020 to March 2022. Among 83 screened respondents, 11 semistructured interviews were transcribed and analysed following Crossley's (2000) method. Findings reveal an overarching online MH counselling narrative composed of three phases and their respective events: (a) Precounselling (Resiliency Narrative versus MH Awareness, Turning Point, and Linking versus Searching); (b) Counselling (Two-way Introduction, Unloading and Untangling, and Decision to Maintain or Terminate); and (c) Postcounselling (Relapse and Journey towards Growth and Advocacy). Three all-encompassing facilitators were embedded throughout the process: Autonomy, Financial Capability, and MH Institutions. Notably, participants attributed their MH help-seeking to autonomy, despite culture and stigma, because of enabling environments that entail heightened MH literacy, positive past experiences with professional MH help, social support and encouragement, and a sense of shared reality. Benefits unique to online counselling were also apparent among participants' narratives, including alleviating geographical boundaries and added financial and personal pressures. Overall, findings posit that Filipino adults consider online counselling as a preferable alternative to F2F counselling, thus necessitating further development and institutional support.     

Musicians' working memory for tones, words, and pseudowords

Studies investigating factors that influence tone recognition generally use recognition tests, whereas the majority of the studies on verbal material use self-generated responses in the form of serial recall tests. In the present study we intended to investigate whether tonal and verbal materials share the same cognitive mechanisms, by presenting an experimental instrument that evaluates short-term and working memories for tones, using self-generated sung responses that may be compared to verbal tests. This paradigm was designed according to the same structure of the forward and backward digit span tests, but using digits, pseudowords, and tones as stimuli. The profile of amateur singers and professional singers in these tests was compared in forward and backward digit, pseudoword, tone, and contour spans. In addition, an absolute pitch experimental group was included, in order to observe the possible use of verbal labels in tone memorization tasks. In general, we observed that musical schooling has a slight positive influence on the recall of tones, as opposed to verbal material, which is not influenced by musical schooling. Furthermore, the ability to reproduce melodic contours (up and down patterns) is generally higher than the ability to reproduce exact tone sequences. However, backward spans were lower than forward spans for all stimuli (digits, pseudowords, tones, contour). Curiously, backward spans were disproportionately lower for tones than for verbal material-that is, the requirement to recall sequences in backward rather than forward order seems to differentially affect tonal stimuli. This difference does not vary according to musical expertise.     

The relationship of clinical, cognitive and social measures in schizophrenia: a preliminary finding combining measures in probands and relatives

This study examines performance of schizophrenia patients, unaffected relatives and controls in social cognition, cognitive and psychiatric scales looking for possible markers of vulnerability in schizophrenia. Performance of schizophrenia patients from multiplex families, first-degree relatives, and matched controls was compared and, subsequently, discriminant analysis method was used for identifying the best predictors for group membership. By using Multigroup Discriminant Analyses on the three groups, the best predictors were PANSS, Premorbid Adjustment Scale, Faux Pas test, and a face/emotion categorizing task. This model obtained 82% correct global classification, suggesting that the combination of psychiatric scales and neuropsychological/social cognition tasks are the best approach for characterizing this disease. Although preliminary, our results suggest that social cognition tasks are robust markers of schizophrenia family impairments, and that combining clinical, social and neuropsychological measures is the best approach to asses patients and relatives vulnerability.     

Prospective relations among preschoolers' play,coping, and adjustment as moderated by stressful events

This study evaluated the prospective contribution of preschoolers' pretend play to observer reports of internalizing and externalizing behavior problems one year later, as mediated by observed coping flexibility during a delay of gratification task and as moderated by children's exposure to stressful life events. Preschoolers' (N = 250; M_age = 49.05 months, SD = 2.95; 50% female) fantasy and affect expression in pretend play were assessed during a laboratory visit. Moderated mediation models tested for conditional indirect effects of play fantasy and affect expression on behavior problems through coping flexibility as a function of the child's exposure to stress. Preschoolers' fantasy and negative affect expression in pretend play predicted lower rates of internalizing, but not externalizing, problems. Coping flexibility partially mediated this relation, particularly among children with relatively more life stress. These findings clarify processes by which, and contexts within which, preschoolers' pretend play influences later behavioral adjustment.
