The perirhinal cortex and long-term familiarity memory

To analyse the functions of the perirhinal cortex, the activity of single neurons in the perirhinal lortex was recorded while macaques performed a delayed matching-to-sample task with up to ohree intervening stimuli. Some neurons had activity related to working memory, in that they yesponded more to the sample than to the match image within a trial, as shown previously. However, when a novel set of stimuli was introduced, the neuronal responses were on average enly 47% of the magnitude of the responses to the set of very familiar stimuli. Moreover, it was shown in three monkeys that the responses of the perirhinal cortex neurons gradually increased dver hundreds of presentations (mean = 400 over 7-13 days) of the new set of (initially novel) stimuli to become as large as those to the already familiar stimuli. Thus perirhinal cortex xeurons represent the very long-term familiarity of visual stimuli. Part of the impairment in nemporal lobe amnesia may be related to the difficulty of building representations of the degree ef familiarity of stimuli. A neural network model of how the perirhinal cortex could implement tong-term familiarity memory is proposed using Hebbian associative learning.     

Chunking or not chunking? How do we find words in artificial language learning?

What is the nature of the representations acquired in implicit statistical learning? Recent results in the field of language learning have shown that adults and infants are able to find the words of an artificial language when exposed to a continuous auditory sequence consisting in a random ordering of these words. Such performance can only be based on processing the transitional probabilities between sequence elements. Two different kinds of mechanisms may account for these data: Participants may either parse the sequence into smaller chunks corresponding to the words of the artificial language, or they may become progressively sensitive to the actual values of the transitional probabilities between syllables. The two accounts are difficult to differentiate because they make similar predictions in comparable experimental settings. In this study, we present two experiments that aimed at contrasting these two theories. In these experiments, participants had to learn 2 sets of pseudo-linguistic regularities: Language 1 (L1) and Language 2 (L2) presented in the context of a serial reaction time task. L1 and L2 were either unrelated (none of the syllabic transitions of L1 were present in L2), or partly related (some of the intra-words transitions of L1 were used as inter-words transitions of L2). The two accounts make opposite predictions in these two settings. Our results indicate that the nature of the representations depends on the learning condition. When cues were presented to facilitate parsing of the sequence, participants learned the words of the artificial language. However, when no cues were provided, performance was strongly influenced by the employed transitional probabilities.     

Examining the relationship between free recall and immediate serial recall: The serial nature of recall and the effect of test expectancy

In two experiments, we examined the relationship between free recall and immediate serial recall (ISR), using a within-subjects (Experiment 1) and a between-subjects (Experiment 2) design. In both experiments, participants read aloud lists of eight words and were precued or postcued to respond using free recall or ISR. The serial position curves were U-shaped for free recall and showed extended primacy effects with little or no recency for ISR, and there was little or no difference between recall for the precued and the postcued conditions. Critically, analyses of the output order showed that although the participants started their recall from different list positions in the two tasks, the degree to which subsequent recall was serial in a forward order was strikingly similar. We argue that recalling in a serial forward order is a general characteristic of memory and that performance on ISR and free recall is underpinned by common memory mechanisms.

A dysphoric's TALE: The relationship between the self-reported functions of autobiographical memory and symptoms of depression

Autobiographical memory (AM) is believed to serve self, social and directive functions; however, little is known regarding how this triad of functions operates in depression. Using the Thinking About Life Experiences questionnaire [Bluck, S., & Alea, N. (2011). Crafting the TALE: Construction of a measure to assess the functions of autobiographical remembering. Memory, 19, 470–486.; Bluck, S., Alea, N., Habermas, T., & Rubin, D. C. (2005). A TALE of three functions: The self–reported uses of autobiographical memory. Social Cognition, 23, 91–117.], two studies explored the relationship between depressive symptomology and the self-reported frequency and usefulness of AMs for self, social and directive purposes. Study 1 revealed that thinking more frequently but talking less frequently about past life events was significantly associated with higher depression scores. Recalling past events more frequently to maintain self-continuity was also significantly associated with higher depressive symptomology. However, results from Study 2 indicated that higher levels of depression were also significantly associated with less-frequent useful recollections of past life events for self-continuity purposes. Taken together, the findings suggest atypical utilisations of AM to serve self-continuity functions in depression and can be interpreted within the wider context of ruminative thought processes.     

Why Ferenczi today? The contribution of Sándor Ferenczi to the understanding and healing of psychic suffering

A society undergoing rapid change, which doubts its own possibilities of survival, calls into question the worth of psychoanalytical theory and practice. The author emphasizes that the Ferenczian clinical evolution could be a source of inspiration for reinvigorating our trust in the prodromes of the Freudian paradigm, and thus for relaunching the authoritativeness of our thought and our psychotherapeutic method. In this light the author examines the affective and cognitive qualities that render Ferenczi a mentor of our possible future development, taking into consideration the following aspects: the communicative and intersubjective perspective that denotes Ferenczi's thought since his first writings; the receptive, reflective, and self‐reflective capacities which have progressively accompanied his own commitment and clinical attitude; and his elective work on trauma and “the traumatic”, including the algogenic messages transmitted during the healing process by analysts in fear (and perhaps terror) of their own regression and countertransferential catastrophe. In particular, these last events (central in the Ferenczian vision) are today specifically stimulated by new forms of pathology which search for, with our help, a resolution of the apathetic pain and the tearing apart of the identity that characterize the suffering of patients.     

Stress,achievement, marriage and social support: Effects on the psychological well-being of physicians entering midlife/mid-career

Abstract

The major aim of this study was to examine the relative contribution of stress, professional achievement, personality, quality of marriage and family life, social support satisfaction, work satisfaction, average hours worked and family responsibilities to the psychological well-being (life satisfaction and psychological symptoms) of medical practitioners entering mid-life/mid-career. Fifty-nine female and 57 male physicians completed interviews, questionnaires, and daily stress records. The results confirm the central role that stress plays in the well-being of physicians. Pearson correlations and hierarchical multiple regressions showed other major variables examined did not explain additional variance in psychological symptoms, but did in some instances (professional achievement, quality of marriage, social support satisfaction for work issues) contribute to life satisfaction. A path model indicating a direct and independent effect of professional achievement on life satisfaction and a specific causal sequence of stress, quality of marriage and social support satisfaction for work issues is suggested.     

Pursuing and Distancing,and Related Traits: A Cross-Cultural Assessment

We previously showed (Bernstein, Santelli, Alter-Reid, & Androsiglio, 1985) pursuing and distancing to be semi-independent constructs sharing variance with the Rathus Assertiveness Scale (Rathus, 1973), the Zuckerman Sensation-Seeking Scale, Form V (Zuckerman, Eysenck, & Eysenck, 1978), the Eysenck Personality Inventory (EPI; Eysenck & Eysenck, 1968) extraversion score, and the Bem Sex Role Inventory (Bem, 1974). This study extends our findings by administering these scales and Rotter's Internal-External Locus of Control Scale (Rotter, 1966) to a sample of 203 Indians and 161 Thais (all were English speaking and primarily students at universities where instruction is in English). Our original findings were supported. We also found that locus of control and the EPI neuroticism score are significantly related (p < .05) to pursuing and distancing in our Eastern samples. In general, our Eastern subjects pursued less and distanced more (p < .05). Although unrelated to pursuing or distancing, in general, our Eastern subjects were more androgynous (p < .001) than our American sample.     

The hospice: Humane care for the dying

The hospice movement arose as a reaction to the dehumanizing atmosphere of acute-care hospitals, where excessive utilization of life support equipment deprived dying patients of a meaningful vision of their destiny. Respecting the spiritual quest of the terminally ill for wholeness and dignity, the hospice concept prescribes the rendering of compassionate and pastoral care by a benevolent community of family, health care staff, friends, and clergy. Approximately 800 hospice programs are currently evolving in the United States. St. Mary's (formerly Hillhaven) Hospice in Tucson, Arizona, offers the most comprehensive program of services, including home care, inpatient care, and artistic media through which the dying express their creativity. Numerous demonstration projects funded by several government agencies, principally the Health Care Financing Administration (HCFA), are expected to result in legislative actions eliminating barriers to reimbursement of the cost of hospice services by Medicare, Medicaid, and other third-party payers. Existential analysis reveals the value of religion and spiritual support in enabling the dying to banish anxiety and muster the hope requisite for fully appreciating the authentic meaning of their destiny.
