The effects of age on sensory thresholds and temporal gap detection in hearing, vision, and touch

Differences in sensory function between young (n 5 42, 18—31 years old) and older (n 5 137, 60—88 years old) adults were examined for auditory, visual, and tactile measures of threshold sensitivity and temporal acuity (gap-detection threshold). For all but one of the psychophysical measures (visual gap detection), multiple measures were obtained at different stimulus frequencies for each modality and task. This resulted in a total of 14 dependent measures, each based on four to six adaptive psychophysical estimates of 75% correct performance. In addition, all participants completed the Wechsler Adult Intelligence Scale (Wechsler, 1997). Mean data confirmed previously observed differences in performance between young and older adults for 13 of the 14 dependent measures (all but visual threshold at a flicker frequency of 4 Hz). Correlational and principalcomponents factor analyses performed on the data from the 137 older adults were generally consistent with task and modality independence of the psychophysical measures.     

Post-event spontaneous intrusive recollections and strength of memory for emotional events in men and women

Spontaneous intrusive recollections (SIRs) follow traumatic events in clinical and non-clinical populations. To determine whether any relationship exists between SIRs and enhanced memory for emotional events, participants viewed emotional or neutral films, had their memory for the films tested two days later, and estimated the number of SIRs they experienced for each film. SIR frequency related positively to memory strength, an effect more pronounced in the emotional condition. These findings represent the first demonstration of a relationship between SIRs occurring after an emotional experience and subsequent memory strength for that experience. The results are consistent with the possibility that emotional arousal leads both to elevated SIR frequency and better memory, and that the covert rehearsal associated with SIRs enhances memory for emotional relative to neutral stimuli. Additional evidence of menstrual cycle influences on SIR incidence in female participants appears to merit consideration in future work.     

Trans-parency in the workplace: How the experiences of transsexual employees can be improved

Very little research has focused exclusively on the workplace experiences of transsexual employees. Studies that have been done are either qualitative case studies (e.g., Budge, Tebbe, & Howard; 2010; Schilt & Connell, 2007), or aggregate transsexual individuals with lesbian, gay, and bisexual employees (e.g., Irwin, 2002). The current study focuses on this underexamined population and examines general workplace experiences, and both individual and organizational characteristics that influence transsexual employees' job attitudes. Results reveal that organizational supportiveness, transsexual identity centrality, and the degree to which they disclose to individuals outside of work all predict transsexual employees' disclosure behaviors in the workplace. These disclosure behaviors are positively related to job satisfaction and organizational commitment, and negatively related to job anxiety. These relations are mediated by coworker reactions. This research expands knowledge about diverse employee populations and offers both theory and some of the first large-scale empirical data collected on the workplace experiences of transsexual employees.     

Experience with proactive interference diminishes its effects: mechanisms of change

In three experiments, we examined the mechanisms by which prior experience with proactive interference (PI) diminished its effects. Cued recall tasks conforming to an A–B, A–D paradigm were used to induce PI effects. Experiment 1 showed that reduced PI was not due to a reduction in attention to the source of PI. Experiment 2 revealed that participants’ awareness of PI effects on memory performance increased with experience, resulting in a shift in encoding processes. Experiment 3 demonstrated that changes in encoding provided additional support for recollection that further enhanced participants’ ability to constrain their retrieval processing to the appropriate source of information at the time of test. These results can be interpreted as showing that experience with PI enhances awareness of its effects and allows individuals to adjust their learning and retrieval strategies to compensate for such effects.     

H.M.'s personal crossword puzzles: Understanding memory and language

The amnesic patient H.M. has been solving crossword puzzles nearly all his life. Here, we analysed the linguistic content of 277 of H.M.'s crossword-puzzle solutions. H.M. did not have any unusual difficulties with the orthographic and grammatical components inherent to the puzzles. He exhibited few spelling errors, responded with appropriate parts of speech, and provided answers that were, at times, more convincing to observers than those supplied by the answer keys. These results suggest that H.M.'s lexical word-retrieval skills remain fluid despite his profound anterograde amnesia. Once acquired, the maintenance of written language comprehension and production does not seem to require intact medial temporal lobe structures.     

Political Dimensions of Pastoral Care in Community Disaster Responses

All caregiving takes place in multiple political contexts and assumes or actually furthers various political agendas, whether acknowledged or not. When strategically incorporated into pastoral and spiritual care, politically responsive actions may enhance the practice of care. When disaster strikes a community, ritual engagement of the larger public context provides a significant opportunity for pastoral caregivers to function as public pastoral theologians and to influence the corporate response to communal challenges. In these circumstances of community vulnerability, pastoral caregivers and communities of faith are positioned to provide spiritual care that combines solace and safety for the victims with guidance and shaping influence on the ritual practices and rhetorical interpretations called upon to assist the community to endure, respond, and heal. This article examines some central political aspects of the pastoral caregiver’s repertoire that might further a stricken community’s ritual and rhetorical resources necessary to sustain life, share loss, reclaim goodness, and rebuild for a strong future. Drawing upon a view of lamentation as a tri-partite process of sharing anguish, interrogating causes, and reinvesting in hope, I suggest how the spiritual and pastoral caregiver may collaboratively participate in a “disaster-response matrix” that organizes corporate responses to catastrophic disaster. This article pays particular attention to macro-, meso-, and micro-level political negotiations necessary to ensure respect for diversity and shared responsibility in creating rituals, memorials, and public narratives at the onset of disaster and in its aftermath over the generations. Illustrations from the experience of religious caregivers at Columbine, Hurricane Katrina, 9/11, Aurora, Newtown, and Boston are presented to guide pastoral engagement of civil society in disruptive times.     

Explanation,Contrast, and the Primacy of Practice

Abstract: The common practice of giving (comparing, rejecting and inferring) explanations of phenomena is at the root of articulate learning, including the enterprises we collect under the noun ‘science’. The way that practice privileges a single item from the myriad relevant to any phenomenon tells us something about articulateness itself.     

How working memory and cognitive modeling functions of the cerebellum contribute to discoveries in mathematics

A theory of how connections between working memory (Science 255 (1992) 556; in: G. Bower (Ed.), The Psychology of Learning and Motivation, Vol. 8, Academic Press, New York, p. 47) and cognitive functions of the cerebellum (Trends Neurosci 16(11) (1993) 448; Curr. Opinion Neurobiol. 9 (1999) 718; Behav. Neurosci. 100 (1986) 443, Behav. Neurosci. 103 (1989) 998) lead to mathematical discovery is presented. It is proposed that (a) patterns of repetitious working memory processing are formed in the cerebellum, and (b) when these cerebellar patterns are subsequently fed back to control processing in working memory, they may become cognized in visuospatial imagery and language as the concepts and axioms that underlie mathematical discovery. It is concluded that a neurophysiological explanation of the cognitive origins of mathematics (L. English (Ed.), Mathematical Reasoning: Analogies, Metaphors, and images, Lawrence Erlbaum, Mahwah, NJ, p. 21, where Mathematics comes from: How the embodied mind brings mathematics into being, Basic Books, New York) can be based upon how conceptual constructions arise from the collaborative interactions of working memory and the cognitive functions of the cerebellum.
