The relation between gap discrimination and auditory stream segregation

Gap discrimination and stream segregation were examined using sequences of 2, 4, 8, or 16 tones. The frequency differences between tones ranged from 1/24 to 2 1/2 octaves. Judgments of stream segregation show large intersubject variability, whereas gap thresholds are comparatively stable. Gap thresholds and streaming judgments are both affected by the frequency separation between tones. However, only streaming judgments are affected by presentation rate. Gap-threshold functions show no discontinuities or plateaus with increasing frequency differences and faster presentation rates. These results suggest that stream segregation is not a primary factor limiting gap-discrimination performance in tonal sequences.     

From dispositions to behaviors: The flip side of attribution

The implicational relations between dispositional levels and relevant categories of behavior were investigated. Observers were asked questions about the extent to which persons occupying moderate or extreme positions on an attribute (dispositional) continuum (a) attempt various behaviors, (b) are potentially able to perform various behaviors, and (c) generally emit those same behaviors. Three determinants—central tendency, ability, and social desirabliity—offer a reasonable account of the observed implicational relations. First, persons with a given disposition are not expected to emit behavior that is widely discrepant with that disposition. Second, ability considerations dictate that persons with skillful dispositions are believed capable of unskillful behavior, but unskillful persons are thought relatively incapable of skillful behavior. Third, persons are believed to more frequently attempt socially desirable than socially undesirable behavior. Also, persons with moderate dispositions are believed to actually emit socially desirable behavior more frequently than socially undesirable behavior. Finally, the determinants noted above may be of differing relevance for morality, ability, and preference attributes.     

Syntactic and conversational characteristics of fathers' speech

The verbal interactions of 16 fathers and 16 mothers with their 2-year-olds were assessed during free play. On the basis of the amount of time the father spent with his child weekly, fathers were divided into two groups, those spending a high proportion of time and those spending a low proportion of time. Each parent's speech was coded for a number of syntactic and conversational features. No differences were found between fathers and mothers in the use of these features. Furthermore, the results suggest that the amount of time fathers spend with their children does not dramatically affect the syntactic or conversational features of their speech, since the two groups of fathers did not differ for these features.This research was based on a dissertation submitted to the Pennsylvania State University in partial fulfillment of the requirements for the Ph.D.     

Cognitive masking in rapid sequential processing: The effect of an emotional picture on preceding and succeeding pictures

This experiment assessed the effect of an emotional pictorial input on the processing of preceding and succeeding pictorial inputs. Thirty-nine individual pictures were successively presented for 165 msec, with a 500-msec dark interval between each item. The 20th input item was either an emotional or a neutral picture; the remaining 38 items were neutral sketches. Postinput recognition data indicated a processing disruption of several pictorial items following the emotional as compared to the neutral input and a possible processing disruption of the item immediately preceding the emotional stimulus. The outcome suggests nonindependence in the processing of separate picture inputs in rapid sequential presentations.     

Variables influencing the mode of processing of complex stimuli

The present study attempts to specify some of the conditions under which parallel and serial processing may occur. The three variables studied were (1) type of task, (2) relative set for speed vs accuracy, and (3) practice. Pairs of multidimensional, geometric stimuli were presented either simultaneously or successively to S who was required to indicate whether they were the same or different. Each S participated in nine sessions. For half of the Ss speed was emphasized, and for the other half accuracy was emphasized. The results indicated that: (1) responses were faster with successive presentation than with simultaneous presentation; (2) with successive presentation, processing was serial; (3) in the simultaneous presentation condition, a gradual shift from serial to parallel processing occurred with practice; and (4) the speed and accuracy instructions used in this experiment produced no differential effects on latency or errors.     

Relational ethics in the novels of Charles Williams

In the novels of Charles Williams, characters are faced with the mundane but profound choice between "charity and selfishness," the City and Infamy. Williams' "way of exchange" and "doctrine of substitution" have direct parallels in contextual family therapy. In Descent Into Hell, he explores the long-term effects of legacy and the balancing of the relational ledger through the process of "substituted" love. In All Hallows' Eve, the focus is on forgiveness and the opportunity to correct relational mistakes while one is in a purgatorial state. Both novels include parallel processes of relational stagnation/disjunction and rejunction, illustrating the fact that our simple, everyday choices have ultimate significance.     

Manual Movement in Sign Languages: One Hand Versus Two in Communicating Shapes

In sign languages, the task of communicating a shape involves drawing in the air with one moving hand (Method One) or two (Method Two). Since the movement path is iconic, method choice might be based on the shape. In the present studies we aimed to determine whether geometric properties motivate method choice. In a study of 17 deaf signers from six countries, the strongest predictors of method choice were whether the shape has any curved edges (Method One), and whether the shape is symmetrical across the Y‐axis (Method Two), where the default was Method One. In a second study of ASL dictionary entries for which the movement path of the sign is iconic of an entity's shape, the same predictors surfaced. These tendencies are captured in the Lexical Drawing Principle, which is coherent with biological constraints on movement in general. Drawing in the air with two hands, however, is costly, both cognitively and biomechanically. Furthermore, it distinguishes signers from non‐signers, who draw shapes with only one hand. Signers assume this extra cost in the lexicon because of the enhanced iconicity the possibility of two hands offers; they assume it in drawing shapes in the air because they apply the same linguistic principle they use in the lexicon. Additionally, having a choice of methods allows the signer to benefit from over‐specification in providing redundant information about the shape, enhancing comprehensibility and resolving ambiguity.     

Why Language Matters to Psychoanalysis

Much psychoanalytic vocabulary is embedded in discourses, or languagegames, that involve philosophical assumptions that most post-Freudian, relational, and intersubjective systems analysts no longer accept. Terms like transference, projective identification, and representation, however carefully redefined for contemporary purposes, cannot escape their connotative history and loading. It is suggested that psychoanalytic thinkers and practitioners remain open to questioning and being questioned about our use of words, their impact on our attitudes toward our patients, and about our responsibility for disavowed assumptions about human nature and reality.
