Influence of prolonged deprivation,age and culture on the development of future orientation

Prolonged deprivation and future orientation (FO) were studied in 200 Indian and Nepalese students of 14–16 and 18–20 years with verbal measures. In both cultures low deprived subjects were significantly more future-oriented. In the development of FO both age and deprivation were significant with experiential aspect of socialization exerting greater influence than physico-economic deprivation.     

Tradition religieuse et capacité de pardon

Forgiveness is a fundamental ingredient of everyday life. This article is intended to present, in a synthetic way, a number of recent works having empirically determined the relationship between religious tradition and forgivingness. To forgive is basically to give something to someone. For/give is the equivalent of the latin per/donare. Forgiveness is the gift of one's right to resentment after having been the victim of an offense. Forgiveness has been empirically investigated in two ways. The first approach specifically considered forgiveness as a possible answer to a given situation. The second approach considered forgiveness as a philosophy of life, as a habit; that is, as a personality trait. The studies reported in this article illustrate this second approach. A three-factor model of forgivingness is presented: lasting resentment, sensitivity to the circumstances of the offence, and unconditional forgiveness. It is shown that this model nicely fit empirical data from samples of persons grown up either in the Buddhist tradition, or in the Christian tradition, or in the Hindu tradition. It is also shown that among people grown up in the Muslim tradition this model must be adjusted to reflect the unique character of this tradition: Islam is both a religious and a political tradition. In brief, people whose spiritual references are either Buddhist or Christian or Hindu must be aware that if a conflict, even a minor one, opposes them to Muslims, a particular attention will be attributed to their apologizing behavior and to their efforts to repair the wrong committed. Forgiveness will probably be granted only after the offender has satisfied a number of conditions. Symmetrically, people whose references are Muslim must be aware that, if a conflict opposes them to people grown up in the other traditions, all the circumstances of the situation will probably play a more or less similar role (intention, apology, social proximity) and that forgiveness may be unconditionally granted. Unconditional forgiveness exists, at least in theory, in these traditions: it is not regarded as a weakness or as an immoral disposition.     

An exploration of the Indian mindset

Eight hundred and twenty-nine adults, drawn from 12 locations in all four parts of India, participated in a study that explored the joint effects of Indians’ discrepant mindset, context sensitivity, and quality of environment on their modes of behavior. Respondents also predicted how a person is likely to change his behavior when the conditions in which he works change from disabling to enabling. The findings showed that the two most dominant modes of behavior-self-serving calculative and achieving high positive goal — coexisted, but were differently caused. Context sensitivity facilitated both modes of behavior; but adequate infrastructure and friendly and helpful people in the neighborhood encouraged only achieving high positive goal behavior. On the contrary, duplicity in professing desirable but acting under realistic compulsions, poor quality of environment, and low levels of development were conducive to self-serving calculative behavior. As a situation changed from disabling to enabling, a person was likely to shift towards more positive behavior.     

Assertiveness and Personality: Cross-Cultural Differences in Indian and Serbian Male Students

The present study investigates the differences in assertiveness and the ability to discriminate assertiveness from aggressive and defensive/passive behaviour and the relation among them across Indian and Serbian cultures, besides exploring the relationship between personality and assertiveness in both the cultures. Measures of assertiveness, scale of discrimination among assertive, aggressive and passive behaviour and Big-Five personality inventory were administered on Indian (N = 108) and Serbian (N = 116) engineering students. Results indicated significant difference in the assertive behaviour of Indian and Serbian samples apart from significant relationship between personality and assertiveness.     

Time-dependent transformations of memory representations differ along the long axis of the hippocampus

Research has shown that sleep is beneficial for the long-term retention of memories. According to theories of memory consolidation, memories are gradually reorganized, becoming supported by widespread, distributed cortical networks, particularly during postencoding periods of sleep. However, the effects of sleep on the organization of memories in the hippocampus itself remains less clear. In a 3-d study, participants encoded separate lists of word–image pairs differing in their opportunity for sleep-dependent consolidation. Pairs were initially studied either before or after an overnight sleep period, and were then restudied in a functional magnetic resonance imaging (fMRI) scan session. We used multivariate pattern similarity analyses to examine fine-grained effects of consolidation on memory representations in the hippocampus. We provide evidence for a dissociation along the long axis of the hippocampus that emerges with consolidation, such that representational patterns for object–word memories initially formed prior to sleep become differentiated in anterior hippocampus and more similar, or overlapping, in posterior hippocampus. Differentiation in anterior hippocampal representations correlated with subsequent behavioral performance. Furthermore, representational overlap in posterior hippocampus correlated with the duration of intervening slow wave sleep. Together, these results demonstrate that sleep-dependent consolidation promotes the reorganization of memory traces along the long axis of the hippocampus.

The hippocampus has long been considered critical for encoding new memories; however, the effects of consolidation on hippocampal memory traces has remained an area of active research. Memories are thought to be stabilized for the long term as they become distributed across neocortical networks (Buzsáki 1989; Alvarez and Squire 1994; McClelland et al. 1995), a process supported by mechanisms during sleep (Diekelmann and Born 2010; Rasch and Born 2013). Whereas much research has been devoted to understanding the hippocampal contributions to the long-term retention of memories, open questions remain in considering how sleep-dependent consolidation affects the organization of hippocampal traces.The hippocampus has previously been shown to be critical for binding disparate elements of an experience together (Cohen and Eichenbaum 1993; Davachi 2006). Theories suggest that the hippocampus quickly encodes new experiences, while the cortex, with a slower learning rate, gradually comes to represent the central features from this hippocampal trace, resulting in abstracted memories that can be integrated into long-term cortical stores (McClelland et al. 1995). Prior research has demonstrated evidence for a coordinated hippocampal–cortical dialogue during sleep (Andrade et al. 2011; Bergmann et al. 2012; Ngo et al. 2020) as well as enhanced hippocampal–cortical functional connectivity after learning, facilitating the retention of memories (Tambini et al. 2010; Tompary et al. 2015; Murty et al. 2017; Cowan et al. 2021). Reports suggest consolidation results in more integrated cortical memory traces in the cortex (Richards et al. 2014; Tompary and Davachi 2017; Cowan et al. 2020); however, it remains an open question whether the active consolidation processes that support memory reorganization across hippocampal–cortical networks also transform hippocampal memory traces.Research on the fate of the hippocampal trace with consolidation has often focused on questions about the permanence of memories in the hippocampus. Theories of systems consolidation have classically debated whether the hippocampal trace is time-limited (Alvarez and Squire 1994), or, rather, whether the hippocampus continues to represent memories in perpetuity (Nadel and Moscovitch 1997; Winocur and Moscovitch 2011; Moscovitch et al. 2016; Sekeres et al. 2018a). Another theory posits that while the original hippocampal trace is transient, during retrieval the hippocampus reconstructs details of an experience from cortical traces (Barry and Maguire 2019). Much research in this vein has focused on investigating changes in hippocampal blood-oxygenation level-dependent (BOLD) univariate activation with time (Bosshardt et al. 2005a,b; Takashima et al. 2006, 2009; Gais et al. 2007; Sterpenich et al. 2007, 2009; Yamashita et al. 2009; Milton et al. 2011; Watanabe et al. 2012; Ritchey et al. 2015; Baran et al. 2016; Dandolo and Schwabe 2018) and the effects of hippocampal lesions in animals and humans (Winocur et al. 2001; Frankland and Bontempi 2005; Winocur and Moscovitch 2011; Moscovitch et al. 2016) with mixed results. Interestingly, pinpointing these effects along the long axis of the hippocampus has also proven unclear. Some reports have found that only the anterior hippocampus exhibits time-dependent changes in retrieval-related univariate activation, with evidence of decreases with delay (Takashima et al. 2006; Milton et al. 2011; Dandolo and Schwabe 2018), but also evidence of greater activation for more remote, compared with recent, memories (Bosshardt et al. 2005a,b). At the same time, other studies have found decreases in univariate activation only in the posterior hippocampus (Bosshardt et al. 2005b; Takashima et al. 2009; Yamashita et al. 2009; Milton et al. 2011; Watanabe et al. 2012; Ritchey et al. 2015; Sekeres et al. 2018b).Because of these conflicting findings, instead of asking just about dependence or overall changes in activation in the hippocampus, theories and empirical research have instead increasingly considered the organization of memory representations in the hippocampus (Robin and Moscovitch 2017; Sekeres et al. 2018a). Broadly, using representational similarity analyses, several studies have shown that hippocampal memory representations tend to become differentiated over learning, particularly for memories with overlapping content (LaRocque et al. 2013; Schlichting et al. 2015; Chanales et al. 2017; Brunec et al. 2020). Furthermore, it has been suggested that information is represented at different scales or “granularity” along the long axis of the hippocampus, in line with place field size differences (Kjelstrup et al. 2008; Komorowski et al. 2013), with anterior hippocampus representing more similar, coarse-grained, or gist-like information, while the posterior hippocampus represents fine-grained, detail-oriented representations (Evensmoen et al. 2013; Poppenk et al. 2013; Robin and Moscovitch 2017; Brunec et al. 2018, 2020). However, limited work has investigated whether this representational organization is altered with consolidation. Reports have shown that memory representations sharing overlapping content become more similar over a delay (Tompary and Davachi 2017; Audrain and McAndrews 2020), yet other work has found that hippocampal representations were not modulated by time (Ritchey et al. 2015; Ezzyat et al. 2018). Intriguingly, reports indicating greater differentiation in memories in anterior compared with posterior hippocampus with consolidation (Tompary and Davachi 2017; Dandolo and Schwabe 2018; Ezzyat et al. 2018) raise the possibility that the representational granularity along the anteroposterior axis may be transformed with consolidation. Thus, more work is needed to understand how consolidation influences the representational structure of memories in the hippocampus. In particular, despite much research connecting sleep to consolidation (Diekelmann and Born 2010; Rasch and Born 2013), it remains unknown whether sleep-dependent processes facilitate such delay-dependent transformations to the hippocampus.Active processes in the sleeping brain seem to be optimized for systems consolidation. Currently, the best mechanistic evidence for sleep-dependent consolidation comes from studies on hippocampal replay showing the repeated reactivation of encoding-related patterns of hippocampal activity (Buzsáki 1989; Wilson and McNaughton 1994; Girardeau and Zugaro 2011), which seems to be coordinated with replay in areas of the cortex (Ji and Wilson 2007; Peyrache et al. 2009; Wierzynski et al. 2009). It is thought that the coupling between oscillations during non-REM sleep stages (particularly slow wave sleep [SWS])—including sharp wave ripples that support replay, thalamocortical spindles, and slow oscillations—facilitates the hippocampal–cortical dialogue and information transfer to the cortex (Buzsáki 1996; Sirota et al. 2003; Steriade 2006; Clemens et al. 2011; Mölle and Born 2011; Staresina et al. 2015). Indeed, our previously published work from the present study provided supporting evidence that the density of thalamocortical sleep spindles (11–16 Hz) during overnight sleep is related to enhanced hippocampal–cortical functional connectivity measures, and increased similarity, or greater representational overlap, among memories in the ventromedial prefrontal cortex (vmPFC) (Cowan et al. 2020). Yet, while some prior work has shown that features of sleep, including spindle density and the duration of non-REM SWS, are related to decreased retrieval-related hippocampal activation for memoranda learned prior to sleep (Takashima et al. 2006; Baran et al. 2016; Hennies et al. 2016), it remains unclear how the reactivation of hippocampal traces during replay may impact the way memories are organized along the long axis of the hippocampus.To examine the effects of sleep-dependent consolidation on the neural representation of memories in the hippocampus, we designed a within-participant 3-d study using overnight polysomnography (PSG), functional magnetic resonance imaging (fMRI), and behavioral measures of memory (Fig. 1). In this study, aspects of which have been previously published (Cowan et al. 2020), participants first studied a list of word–image pairs before sleeping overnight (Sleep List), during which PSG was recorded. Upon waking in the morning, participants studied a new list of pairs (Morning List). The word–image pairs from these two lists were then restudied while undergoing an fMRI scan, intermixed with a third, novel list of pairs (Single Study List). Associative memory was tested immediately after the scan and again 24 h later. We compared measures of multivariate pattern similarity and univariate BOLD signal for the lists learned prior to, or after, sleep to probe how modulating the opportunity for sleep-dependent consolidation impacts the way memories are organized across the long axis of the hippocampus. Furthermore, our design allowed us to examine how features of overnight sleep are related to the representational organization of memories learned prior to the sleep period, as well as the behavioral benefit of changes to the organization of these memories. Thus, our study provides a novel examination of the effects of sleep-dependent consolidation on the representation of memories along the long axis of the hippocampus.Open in a separate windowFigure 1.Study design. For all encoding and restudy sessions, participants were asked to form an association between a word and an image. Participants first encoded the Sleep List (blue) before sleeping overnight while polysomnography was recorded. The next morning (day 2), participants encoded a second set of novel word–image pairs (Morning List). After a short delay (∼2 h), participants restudied these two sets of pairs, intermixed with novel pairs (Single Study List) in the functional magnetic resonance imaging (fMRI) scanner. Source memory was tested immediately after the scan and after a 24-h delay (day 3).     

Conceptualizations of Forgiveness and Forgivingness Among Hindus

The conceptualizations about forgiveness of Indians from the Hindu community were explored using the Conceptualizations of Forgiveness Questionnaire. As expected, the four-factor structure of conceptualizations found among Western Europeans from Christian backgrounds (Encourages Repentance, Immoral Behavior, Broad Process, and Change of Heart) fit the data collected among the Hindus. Hindus' propensity to forgive was also explored using the Forgivingness Questionnaire. As expected, the three-factor structure of forgivingness found among Europeans (Lasting Resentment, Sensitivity to Circumstances, and Unconditional Forgiveness) fit the data collected among the Hindus. Finally, it was shown that, among Hindus, the relationships between conceptualizations about forgiveness and propensity to forgive were basically the same as the ones found among Western Europeans.     

Heart Rate and Affective Reactions to State Self-Objectification as a Function of Gender

The purpose of the present study was to examine heart rate (HR) and affective reactions to state self-objectification as a function of gender. We examined negative affect, positive affect, guilt, and HR at 6-second and 5-minute intervals across baseline, control, high objectification, low objectification, and cologne conditions in men (n = 53) and women (n = 57). Mixed factorial MANOVA results indicated a statistically significant Gender × Condition interaction. Both men and women showed a cardiac orienting response to high versus low objectification. Cardiac stress reactions to objectification were higher among women. Negative affective reactions to objectification were more pervasive across conditions among women.     

Child Sexual Abuse in India: Current Issues and Research

Child sexual abuse (CSA) is a serious and widespread problem in India as it is in many parts of the world today. The trauma associated with sexual abuse can contribute to arrested development, as well as a host of psychological and emotional disorders, that some children and adolescents may never overcome. When sexual abuse goes unreported and children are not given the protective and therapeutic assistance they need, they are left to suffer in silence. This article discusses the nature and incidence of the sexual abuse of minors in India and presents an overview of research findings to date. Socio-cultural and familial risk factors involved in CSA are discussed. Common symptoms and disorders associated with sexual abuse are outlined. Finally, some implications for counselors working with children in India who have been sexually abused are highlighted.     

Bulk modulus of semiconductors and its pressure derivatives

Expressions for the bulk modulus and its first and second pressure derivatives for group I–VII, II–VI, III–V and IV–IV semiconductor binary compounds are derived using an ab initio pseudopotential approach to the total crystal energy within the framework of local density functional formalism. The computed results are very close to the available experimental data.     

The Role of Attachment Style and Depression in Patients with Hepatitis C

Patients infected with chronic hepatitis C virus (HCV) commonly suffer from the triad of depression, pain and fatigue. This symptom triad in HCV is likely influenced by additional psychological and interpersonal factors, although the relationship is not clearly understood. This retrospective study aimed to characterize the relationship between attachment style and depressive and physical symptoms in the HCV-infected population. Over 18 months, 99 consecutively referred HCV infected patients were assessed with the Hamilton Depression Rating Scale (HDRS), Fatigue Severity Scale, Patient Health Questionnaire-15 for physical symptoms and the Relationship Questionnaire for attachment style. An ANOVA was used to identify differences between attachment styles and Pearson correlations were used to evaluate the association between depression, fatigue and physical symptoms. Approximately 15 % of patients in the sample had a fearful attachment style. Patients with fearful attachment style had significantly higher depressive symptoms compared to a secure attachment style (p = .025). No differences in physical and fatigue symptoms were observed between attachment styles. Further, HDRS scores were significantly associated with fatigue scores (p < .001) and physical symptoms (p < .001), reinforcing the relationship between these symptom domains in HCV-infected patients. Although depressive, physical and fatigue symptoms are inter-related in HCV-infected patients, our study results suggest that only depressive symptoms were influenced by the extremes of attachment style. Screening of relationship styles may identify at-risk HCV-infected individuals for depression who may have difficulty engaging in care and managing physical symptoms.
