The nature of the phonological disorder in conduction aphasia

Sequences of attempts to name pictured objects were used to examine phonological dysfunction in three diagnostic subgroups of aphasia. A prevalence of "phonologically-oriented sequences" (i.e., those sequences that contained only attempts with a phonological resemblance to the target word) was found to be a diagnostic criterion for conduction aphasia. When compared to a group of Broca's (n = 7) and Wernicke's (n = 5) aphasics, all the conduction aphasics (n = 6) produced proportionately more of such phonologically-oriented sequences on a picture naming test. An examination of the phonologically-oriented sequences produced by the conduction aphasics indicates that speech production in conduction aphasia involves dysfunction at an early stage of sound-encoding. The theoretical implications of this view are discussed.     

Language and the young stutterer: A new look at old theories and findings

The major theories and research approaches as to the etiology and development of stuttering are reviewed from a historical perspective. Findings are drawn from different sources indicating that language deficits are an initial contributing factor and a continuing component of this disorder. Those subsets of children which constitute high-risk groups are identified. It is suggested that researchers begin investigating the underlying organic bases of stuttering and its relationship to stages of language development. Finally, clinicians are encouraged to employ a therapy program that is concerned with all areas of language, rather than emphasizing treating only the symptoms of stuttering behavior.     

The empirical base of Trope's position on achievement-task choice: A critique

The empirical base of Trope's position on achievement-task choice is critiqued here. Attention is focused on Trope's earliest studies (Trope, 1975; Trope & Brickman, 1975) because they provide this position's most critical tests. Support for the following three propositions of the position is assessed: (1) diagnosticity information, rather than task difficulty information, is the basis of task selection; (2) desire for information about one's ability, not the wish for certain affective consequences, is what motivates achievement-task choice; and (3) the success of the Atkinson model is owed to the adventitious confounding existing between task diagnosticity and task difficulty, and the resulting confounding between ability-informational and affective consequences. The major findings are that (1) the tests of all propositions have such serious logical flaws that they cannot answer the questions they seek to answer, (2) the task choice situation containing the diagnosticity manipulation employed by Trope is so different from real-life task choice situations as to call into question the relevance of Trope's findings for the latter situations, (3) Trope's diagnosticity manipulation is a meaningless one as it gives rise to situations that are logical impossibilities (e.g., skill tasks that are performed equally well by high- and low-skilled people), and (4) the tests of Atkinson's position are invalidated by a serious misinterpretation of that position by Trope.     

Message therapy: Language approach to stuttering therapy with children

Message therapy is a clinical procedure designed to be used as a carry-over technique with school-age stutterers or as a sole technique with the preschooler. The focus of therapy is on a unit of communication rather than on the moment or place of stuttering. One of the basic assumptions of the procedure is that the child is beginning to monitor how he/she is speaking rather than what is being communicated (i.e., the “message”)—each task requiring a different cognitive process. The emphasis of the therapy is to redirect the child's attention to “what he/she is saying.” The clinical procedures are discussed as they relate to the specific population.     

A strategic assessment of deliberate self-harm

This paper describes how patients are interviewed in the context of a general hospital after they have been involved in an episode of self-harm. The interview schedule is structured upon the principles of brief therapy, and uses the 'neutral' approach of the Milan Team (Weakland 1974; Palazzoli et al. 1980). The schedule provides information for referring on and has proved to be 'therapeutic' in itself. The method of interviewing has been used in other hospital contexts with families where a member has been referred 'in a crisis' threatening, or indicating suicidal behaviour. It is suggested that the identification of who is involved systemically is of paramount importance, and that this may not involve 'the family' but significant others in the social network. The important systemic involvement of the general practitioner is recognized.     

Effective functioning in dual-career families: an investigation

This study is concerned with the commonalities inherent in diverse psychotherapeutic strategies, despite seemingly discontinuous theoretical stances. Two approaches were evaluated with respect to effective family functioning, viz. Analytical Psychology and Systems Theory. Analytical Psychology posits the growth of conscious awareness in the individual as the source of therapeutic change. Problem centred systems therapy of the family emphasizes the importance of teaching clinically presenting families to negotiate collectively family rules and expectations and thus to allocate and monitor roles via clear and direct verbal communication. Both positions thus stress the reflective mode as a pivotal factor in effective problem solving. Analytical psychology maintains that conscious awareness expands to the extent that the individual integrates the contrasexual aspect of the personality, that is, the affective, expressive mode or 'feminine principle' in the male, or the instrumental, assertive 'masculine principle' in the female. Such individuals are said to be 'androgenous'. It was therefore hypothesized that such individuals would more readily be able to negotiate family rules and expectations in a manner consistent with a major therapeutic thrust of family therapy. These clinically derived hypotheses were subjected to an empirical test by assessing twenty, non-clinical, dual-career families where both parents pursued careers and were therefore presumably both required to share instrumental and affective roles on the basis of mutual agreement. Results indicated that negotiation contributed significantly to successful role fulfilment and effective family functioning, thus substantiating the focus of family therapy strategies upon clear and direct communication and role allocation.     

The role of the accessory and main olfactory systems in maternal behavior of the primiparous rat

The objective of this study was to analyze the respective roles of the main and accessory olfactory systems in the development of maternal behavior in the primiparous Wistar rat. Females underwent one of the following treatments: vomeronasal nerve section (VN), irrigation of nasal cavities with 5% ZnSO4 solution (ZN), surgical control, saline irrigation control, and normal control. Surgical or first irrigation were done before mating occurred. Irrigations were done every 7 days thereafter. The dams and their litters were observed from the day the litter was born (Day 1) through Day 16. Pup weights and temperatures were recorded daily. Home cages were checked daily for changes in nest location and number of times pups were found out of the nest. Retrieving tests were conducted on Days 4, 7, 10, and 13. The following behavioral items were observed: number of pup retrievals , number of times mother nosed or licked pups, percentage of litter returned to nest by end of test, dam self-grooming, dam climbing or rising, and dam digging or burrowing in shavings. The VN dams and their litters were not significantly different from the control dams and their litters on any of the measures taken. The ZN dams and their litters were not significantly different from their controls on all measures except for pup body temperature which was slightly lower from Day 13 through day 16 and pup body weight which was slightly lower from Day 12 through Day 16. Since these differences are very small, they do not seem to indicate a serious deficiency in maternal behavior. The results indicate that adequate maternal behavior develops with either of the two systems intact.     

Adaptive reasoning: Componential and eye movement analysis of geometric analogy performance

The present study explored individual differences in performance of a geometric analogies task. Whereas past studies employed true/false or two-alternative items, the present research included four-alternative items and studied eye movements and confidence judgements for each item performance as well as latency and error. Item difficulty proved to be a function of an interaction between the number of response alternatives and the number of elements in items, especially for subjects lower in fluid-analytic reasoning ability. Results were interpreted using two hypothesized performance strategies: constructive matching and response elimination. The less efficient of these, response elimination, seemed to be used more by lower ability subjects on more difficult items. While two previous theories resemble one or the other of these strategies, neither alone seems to capture the complexity of adaptive problem solving. It appears that a comprehensive theory should incorporate strategy shifting as a function of item difficulty and subject ability.Componential models, based in part on past research, revealed that a justification component was activated and deactivated depending upon the nature of the analogy being solved. In addition, two new components, spatial inference and spatial application, were identified as important on some items, suggesting that different geometric analogy items invoke different cognitive processing components. Thus, a comprehensive theory should also describe component activation and deactivation.     

Information processing abilities in twins reared apart

A battery of information processing measures and psychometric tests of specific and general cognitive abilities was administered to a sample of 105 individuals which included 34 monozygotic and 13 dizygotic reared apart twin pairs or triplets. Correlations between information processing parameters and psychometric abilities as well as twin resemblances for the information processing parameters were examined. In a principal components analysis of the information processing parameters, three components were identified which accounted for 67% of the total variation; Overall Speed of Response (OSR), Speed of Information Processing (SIP), and Speed of Spatial Processing (SSP). OSR was significantly correlated with WAIS IQ, and psychometric measures of verbal reasoning, spatial ability, and perceptual speed and accuracy. SIP was significantly correlated with WAIS IQ, measures of verbal reasoning, and one of the perceptual speed and accuracy measures. SSP was significantly correlated with measures of both spatial ability and perceptual speed and accuracy. Due to the small size of the dizygotic twin sample, no strong conclusions could be drawn regarding the magnitude of their resemblance. The correlation between component scores of reared apart monozygotic twins was significant for OSR, but not for SIP or SSP.
