Phonological similarity neighborhoods and children’s short-term memory: Typical development and dyslexia

In this article, we explore whether structural characteristics of the phonological lexicon affect serial recall in typically developing and dyslexic children. Recent work has emphasized the importance of long-term phonological representations in supporting short-term memory performance. This occurs via redintegration (reconstruction) processes, which show significant neighborhood density effects in adults. We assessed whether serial recall in children was affected by neighborhood density in word and nonword tasks. Furthermore, we compared dyslexic children with typically developing children of the same age or reading level. Dyslexic children are held to have impaired phonological representations of lexical items. These impaired representations may impair or prevent the use of long-term phonological representations to redintegrate short-term memory traces. We report significant rime neighborhood density effects for serial recall of both words and nonwords, for both dyslexic and typically developing children.     

Attempts to control unwanted thoughts in the night: development of the thought control questionnaire-insomnia revised (TCQI-R)

The attempted control of intrusive, uncontrollable thoughts has been implicated in the maintenance of a range of psychological disorders. The current paper describes the refinement of the Thought Control Questionnaire Insomnia (TCQI; Behav. Cogn. Psychoth. 29 (2001)) through its administration to a sample (n=385) including good sleepers and individuals with insomnia. Several items with poor psychometric properties were discarded, resulting in a 35-item revised TCQI. Factor analysis revealed six factors; aggressive suppression, cognitive distraction, reappraisal, social avoidance, behavioural distraction, and worry. The attempted management of unwanted thoughts was compared across individuals with insomnia and good sleepers, and the impact of these strategies on sleep quality, anxiety and depression was investigated. With the exception of cognitive distraction, individuals with insomnia, relative to good sleepers, more frequently used every thought control strategy. The strategies of aggressive suppression and worry, in particular, appeared to be unhelpful, with the use of these strategies predicting sleep impairment, anxiety and depression. The strategy of cognitive distraction appeared to be helpful, with the use of this strategy predicting better sleep quality.     

The Relationship of the Self of the Therapist to Therapy Process and Outcome: are Some Questions Better Left Unanswered?

Gurman (1987) has challenged the field of marital and family therapy to answer questions concerning the relationship of the therapist to outcome. An examination of conceptual and empirical literature regarding the relationship of the self of the therapist to process and outcome in marital and family therapy discloses that empirical evidence for such relationship is not persuasive. The author constructs a crucible for the field of marital and family therapy.     

Binocular Rivalry Disrupts Visual Priming

Many results implicate perceptual processing in repetition priming, but little is known of potential mechanisms for priming. A new method was used to help determine the processing stage at which priming occurs. Priming pictures were presented under dominance or suppression generated by binocular rivalry. Although low-level, sensory attributes can be processed under rivalry suppression, there is no evidence that repetition priming can be supported by such low-level processing. Priming was found only for stimuli that were processed sufficiently to be identified in the priming stage. The results demonstrate that repetition priming requires processing of stimulus attributes into relatively high-level representations.     

Residual ability to use grapheme-phoneme conversion rules in phonological dyslexia

A case of acquired phonological dyslexia is described (P.M.). The patient was encouraged to read nonwords by analogy with real words, i.e., by changing phonemes in real words to produce pronounceable nonwords. P.M. was able to perform this task suggesting that he retained some ability to use grapheme-phoneme conversion rules. On the basis of P.M.'s performance an additional connection in Morton's logogen model is postulated.     

The visual system of the cat

So much of our current knowledge about the neurophysiology of vision has come from studying the visual system of the cat. Using microelectrode techniques, neurophysiologists have examined in great detail the spatial properties of receptive fields of neurons at various levels of the feline nervous system, and headway is now being made in discovering the patterns of neural connections which give rise to the remarkable degree of stimulus selectivity characteristic of these neurons. This paper reviews the major findings concerning the visual system of the normal adult cat, from optics to visual cortex, and summarizes the physiological consequences of early visual deprivation on the visual nervous system of the cat. The review concludes with remarks about the validity of generalizing from cat neurophysiology to human vision.     

Counselor Sex Role Orientation,Flexibility, and Working Alliance Formation

The authors examined the hypothesized relationship among counselor androgyny, counselor flexibility, and the establishment of client-rated working alliances. In Study 1, 41 counseling students completed the Bem Sex-Role Inventory (BSRI; Bem, 1981a) and the Counselor Behavior Analysis Inventory (Gabbard, Howard, & Dunfee, 1986). Contrary to the hypothesis, there was no relationship between androgyny and counseling flexibility. In Study 2, 42 counseling students completed the BSRI and videotaped counseling sessions with a recruited client. Analyses revealed a significant relationship between counselor flexibility and client ratings of working alliance, but no relationship between counselor androgyny and counselor flexibility. Research and clinical implications are discussed.     

A macintosh interface to teach 3-D perception cues

I present an interface between a Macintosh computer and a pair of glasses with liquid crystal shutter lenses that allow interactive demonstration and investigation of the visual system. This equipment allows a graphic image to be presented to a subject’s eyes in a variety of ways. A primary application of this apparatus has been to create binocular disparity that results in a convincing illusion of depth. Other possible applications include tachistoscopic functions and monocular visual presentations.     

The effects of a self-management treatment package on daily step count in university students with depressive symptoms

Research demonstrates that exercise can decrease depressive symptoms, yet it is infrequently prescribed as an intervention. Self-management techniques offer an effective and cost-efficient approach to increase engagement in physical activity. The purpose of this study was to evaluate the efficacy of goal setting, self-monitoring, and feedback for increasing daily step count in university students (N = 4) reporting depressive symptoms. The treatment was efficacious for increasing steps for three participants with varying levels of consistency. All participants showed a decrease in some depression symptoms on the University Student Depression Inventory. Expert ratings on the Clinical Global Impression Scale indicated improvement in global functioning for three participants. Additional research is needed to determine the efficacy of this intervention package for increasing daily steps and the relation to depression symptoms.     

How context influences predominance during binocular rivalry

Variations in the predominance of an object engaged in binocular rivalry may arise from variations in the durations of dominance phases, suppression phases, or both. Earlier work has shown that the predominance of a binocular rival target is enhanced if that target fits well-via common color, orientation, or motion-with its surrounding objects. In the present experiments, the global context outside of the region of rivalry was changed during rivalry, to learn whether contextual information alters the ability to detect changes in a suppressed target itself. Results indicate that context will maintain the dominance of a rival target, but will not encourage a suppressed target to escape from suppression. Evidently, the fate of the suppressed stimulus is determined by neural events distinct from those responsible for global organization during dominance. To reconcile diverse findings concerning rivalry, it may be important to distinguish between processes responsible for selection of one eye's input for dominance from processes responsible for the implementation and maintenance of suppression.
