Episodic memory deficits slow down the dynamics of cognitive procedural learning in normal ageing

Cognitive procedural learning is characterised by three phases, each involving distinct processes. Considering the implication of episodic memory in the first cognitive stage, the impairment of this memory system might be responsible for a slowing down of the cognitive procedural learning dynamics in the course of ageing. Performances of massed cognitive procedural learning were evaluated in older and younger participants using the Tower of Toronto task. Nonverbal intelligence and psychomotor abilities were used to analyse procedural dynamics, while episodic memory and working memory were assessed to measure their respective contributions to learning strategies. This experiment showed that older participants did not spontaneously invoke episodic memory and presented a slowdown in the cognitive procedural learning associated with a late involvement of working memory. These findings suggest that the slowdown in the cognitive procedural learning may be linked with the implementation of different learning strategies less involving episodic memory in older participants.     

Family Members' Retrospective Perceptions of Intrafamilial Relationships

Parents and daughters in 21 families of women with borderline personality disorder (BPD), 23 women with restricting anorexia nervosa (AN), and 25 women without clinical histories (NC) responded to the Parental Bonding Instrument (PBI) and the Beavers Self-Report Family Inventory (SFI). On the PBI, BPD daughters' perceptions differed from both their parents' whereas AN daughters' perceptions differed from their mothers'. On the SFI, both groups reported less family health than their parents. On both instruments, nonclinical daughters' perceptions were congruent with the parents'. These findings have implications for researchers and therapists for integrating and utilizing the varying perceptions of family members.     

Conceptualizing Coping: Optimism as a Case Study

Coping involves any effort to deal with difficult or challenging situations, and coping strategies vary, often depending on individual differences and situational circumstances. Research has typically characterized coping as either involving problem‐focused or emotion‐focused strategies, or sometimes approach or avoidance strategies. The current review suggests that a more useful distinction would be found in crossed dimensions, such as problem‐focused approach or avoidance, or emotion‐focused approach or avoidance. For example, the individual difference of dispositional optimism has been found to be positively associated with approach coping strategies seeking to solve or control either problems or emotions, depending on the type of stressor. Although widely used, current coping scales may contribute to a skewed view of coping strategies and may not adequately depict coping dimensions. The current review calls for revisions of current scales or creation of new and better scales.     

When educational supervision meets clinical supervision: what can we learn from the discrepancies?

The authors question the taken-for-granted notion of supervision. Their concerns arose out of an attempt to introduce 'clinical' supervision into academia as a way of addressing an increasing number of the ethical issues which confront lecturers. They recognise that knowledge can impact adversely on students and that lecturers at times find themselves compromised. They settled on supervision as an organisational space in the domain of power in which to address the distress they observed. However, through their different experiences of supervision, they soon found themselves talking past each other. When clinical supervision meets educational supervision, several anomalies are brought to the fore. The authors draw on Foucault's notion of discourse, and of knowledge as power, in order to foreground these and conclude by cautioning against an uncritical acceptance of supervision as an ethical practice. They believe there is a benefit in bringing together the two discourses of clinical and educational supervision for further discussion.     

Relations between emotion,memory, and attention: Evidence from taboo Stroop,lexical decision,and immediate memory tasks

This article reports five experiments demonstrating theoretically coherent effects of emotion on memory and attention. Experiments 1-3 demonstrated three taboo Stroop effects that occur when people name the color of taboo words. One effect is longer color-naming times for taboo than for neutral words, an effect that diminishes with word repetition. The second effect is superior recall of taboo words in surprise memory tests following color naming. The third effect is better recognition memory for colors consistently associated with taboo words rather than with neutral words. None of these effects was due to retrieval factors, attentional disengagement processes, response inhibition, or strategic attention shifts. Experiments 4 and 5 demonstrated that taboo words impair immediate recall of the preceding and succeeding words in rapidly presented lists but do not impair lexical decision times. We argue that taboo words trigger specific emotional reactions that facilitate the binding of taboo word meaning to salient contextual aspects, such as occurrence in a task and font color in taboo Stroop tasks.     

VoiceRelay: Voice key operation using Visual Basic

Using a voice key is a popular method for recording vocal response times in a variety of language production tasks. This article describes a class module called VoiceRelay that can be easily utilized in Visual Basic programs for voice key operation. This software-based voice key offers the precision of traditional voice keys (although accuracy is system dependent), as well as the flexibility of volume and sensitivity control. However, VoiceRelay is a considerably less expensive alternative for recording vocal response times because it operates with existing PC hardware and does not require the purchase of external response boxes or additional experiment-generation software. A sample project demonstrating implementation of the VoiceRelay class module may be downloaded from the Psychonomic Society Web archive,www.psychonomic.org/archive.     

Parents' adjustment to late abortion,stillbirth or infant death: the role of causal attributions

The aim of the present study was to explore the attributional processes and the effect of various causal attributions on post-traumatic symptomatology among 110 parents who had lost an infant. The attributional processes were examined with longitudinal data collected over 12 months. One to four weeks post-loss, approximately half of the parents reported that they were never or rarely concerned with attributing responsibility for their baby's death. The importance of attributing responsibility was associated with several post-traumatic symptoms, as was searching for meaning in the death. Attributions to oneself, others, or God were positively and significantly associated with numerous post-traumatic symptoms. The results are discussed with reference to other studies dealing with the effect of attributions on subsequent adjustment among victims of trauma.     

Isolating phonological components that increase tip-of-the-tongue resolution

Three experiments investigated the role of specific phonological components in priming tip-of-the-tongue (TOT) resolution. When in a TOT state, participants read a list of words that included phonological primes intermixed among unrelated words. The phonological primes contained either the same first letter as the target (Experiment 1), a single syllable (first, middle, or last) of the target (Experiment 2), or the first phoneme or first syllable of the target (Experiment 3). Reading first-letter primes in Experiment 1 did not help to resolve TOTs, whereas reading first-syllable primes significantly increased word retrieval in Experiment 2. Experiment 3 replicated the results of Experiments 1 and 2 using first-phoneme primes instead of first-letter primes and using two primes instead of three, although first-syllable priming occurred only for primes read silently. The results of these experiments support a transmission deficit model, where TOTs are caused by weak connections among phonological representations and can be resolved through internal or overt production of specific phonology.     

Syntactic frame and verb bias in aphasia: plausibility judgments of undergoer-subject sentences

This study investigates three factors that have been argued to define "canonical form" in sentence comprehension: Syntactic structure, semantic role, and frequency of usage. We first examine the claim that sentences containing unaccusative verbs present difficulties analogous to those of passive sentences. Using a plausibility judgment task, we show that a mixed group of aphasics performed significantly better on unaccusatives than on passives. We then turn to the observation that passives are generally harder than actives for aphasics. We show that this effect is modulated by lexical bias, i.e., the likelihood that a verb appears in a given syntactic structure: Passives of passive-bias verbs were significantly easier than passives of active-bias verbs. More generally, sentences whose structure matches the lexical bias of the main verb are significantly easier than sentences in which structure and lexical bias do not match. These findings suggest that "canonical form" reflects frequency and lexical biases.     

Blinking predicts enhanced cognitive control

Recent models have suggested an important role for neuromodulation in explaining trial-to-trial adaptations in cognitive control. The adaptation-by-binding model (Verguts & Notebaert, Psychological review, 115(2), 518–525, 2008), for instance, suggests that increased cognitive control in response to conflict (e.g., incongruent flanker stimulus) is the result of stronger binding of stimulus, action, and context representations, mediated by neuromodulators like dopamine (DA) and/or norepinephrine (NE). We presented a flanker task and used the Gratton effect (smaller congruency effect following incongruent trials) as an index of cognitive control. We investigated the Gratton effect in relation to eye blinks (DA related) and pupil dilation (NE related). The results for pupil dilation were not unequivocal, but eye blinks clearly modulated the Gratton effect: The Gratton effect was enhanced after a blink trial, relative to after a no-blink trial, even when controlling for correlated variables. The latter suggests an important role for DA in cognitive control on a trial-to-trial basis.
