The associative learning of the deaf: The effects of word imagery and signability

In two experiments, deaf and hearing subjects learned paired associate lists in which rated visual imagery and signability (a measure of the ease with which a word can be represented as a gestural sign) were orthogonally varied. Visual presentation of three alternating study-recall trials resulted in significant positive effects of imagery for both deaf and hearing subjects, whereas signability facilitated recall only for deaf subjects. Examination of the relation between item attributes and reported learning strategy indicated that both deaf and hearing subjects used imaginal mediators more frequently for high-imagery than low-imagery pairs. A gestural sign strategy was reported almost exclusively by deaf subjects, particularly for high-signability pairs. These results suggest that an examination of the effects of sign language variables will contribute to an understanding of the qualitative differences in the associative learning of the deaf and hearing.     

Doing no more harm than good

Given all the consequences of an act and the value of each of them, how can we find their value ‘on the whole’? In ‘Utilitarianisms: Simple and General’, Inquiry 13, 394–449, J. Howard Sobel offers two alternative suggestions. Here one of Sobel's suggestions is attacked and the other given new support. Where the number of consequences is finite, it is argued, their value is the sum of their basic intrinsic values: the basic intrinsic value of a state of affairs is the value it has on its own account, and not in virtue of other states of affairs it entails.     

Insensitivity to children: Responses of undergraduates to children in problem situations

A study focused on insensitivity of adults to children was presented and discussed. The responses of 100 male and 100 female college undergraduates to hypothetical parent-child problem situations indicated a general lack of communication concerning the child's and their own feelings. However, when the problems involved adult needs being aroused and thwarted, theSs responses were both more insensitive and destructive than when the confrontation centered around only the child's aroused needs. In the latter case theSs did focus their communications more on the child's feelings and how he or she could express them. The results have implications for understanding effective adult behavior and reciprocal adult-child influences on the development of child-behavior dysfunctions.The research reported in this paper was supported in part by Grant MH 16444 from the U.S. Public Health Service, National Institute of Mental Health.The help of Lawrence Messe, Joel Aronoff, Luch Ferguson, and Albert Rabin is very gratefully acknowledged.

Pictures and words in visual search

Ss in three experiments searched through an array of pictures or words for a target item that had been presented as a picture or a word. In Experiments I and II, the pictures were line drawings of familiar objects and the words were their printed labels; in Experiment III, the stimuli were photographs of the faces of famous people and their corresponding printed names. Search times in Experiments I and II were consistently faster when the array items were pictures than when they were words, regardless of the mode of the target items. Search was also faster with pictures than with words as targets when the search array also consisted of pictures, but target mode had no consistent effect with words as array items. Experiment III yielded a completely different pattern of results: Search time with names as targets and faces as search array items was significantly slower than in the other three conditions, which did not differ from each other. Considered in relation to several theories, the results are most consistent with a dual-coding interpretation. That is, items that are cognitively represented both verbally and as nonverbal images can be searched and compared in either mode, depending on the demands of the task. The mode actually used depends on whether the search must be conducted through an array of pictures or words.     

An interactive,interdisciplinary, on-line graphics system for presenting and manipulating directed graphs

An interactive graphics system has been implemented for tutorial purposes and for research in man-machine communication of structural digraphs. An IMLAC intelligent terminal with lightpen input is used in conjunction with a NOVA minicomputer. Successful applications in linguistics and engineering problem solving will be discussed, the latter one in detail.     

Dyadic peer interaction and task orientation in attention-deficit-disordered children

A sequential observational approach was used to compare peer interactions in 10 mixed dyads of ADD-H and non-Add-H boys and 10 dyads of non-ADD-H boys in laboratory cooperative and school classroom task analogue activities. Mixed dyads were found to have a greater frequency of aggression and less joint activity than control dyads in specific situations. No differences were found for measures of functional attention as measured by frequency, duration, and mean duration of task-oriented behavior. Lag sequential analyses revealed two major sequences that differentiated mixed from normal dyads. These were Verbal Reciprocity (a measure of reciprocal verbal interaction) and Retreat (a measure of social withdrawal following aggression).     

Assessing support networks: Stability and evidence for convergent and divergent validity

Data on important methodological problems in assessing support networks is presented. Stability (over 1 year) and construct validity were examined in two groups of mothers of preschool children. One group of mothers had children with a physical handicap (n = 25); the other group had normally developing children (n = 44). When their children were 4 years of age and again at 5 years of age, mothers' support networks were assessed with the Pattison Psychosocial Kinship Inventory (a semistructured interview) and a log diary. Results indicated considerable stability in mothers' support networks over the 1-year period. In addition, agreement across methods was fairly high despite marked differences in format, providing evidence for the construct of support networks. Further evidence for construct validity was provided by generally low correlations between support network variables and other measures of social ecology. Findings were roughly similar for both groups of mothers indicating general replicability of findings.     

Interaction of visual information,verbal information,and linguistic competence in the preschool-aged child

Carol Chomsky found evidence to support the notion that children have not mastered the syntactic form of the sentence John is easy to see until after the age of 8 years. However, she failed to control for the effects the visual stimulus might have had on the child's understanding of the stimulus question. This study reexamined Chomsky's conclusions by using two experimental conditions. The first condition was an exact replication of Chomsky's method, while the second included a control for the biasing effects produced by the visual stimulus. The results confirmed the authors' suspicions that the visual stimulus was indeed distorting Chomsky's findings and that, on the average, children were able to decode this particular syntactic form by the age of 67 months. These findings are discussed from the perspective of Bruner's theory, which states that cognitive processes of children under 8 years of age are dominated by the iconic mode of representation.
