In search of ambiguity

A study of the time required for Ss to perceive the two meanings of ambiguous sentences, supports the following conclusions: (I) Perception time (PT) is a function of the type of ambiguity, three of which are defined in this study. (2) A similar relative function was obtained for thePT in sentences with more than one ambiguity and for sentences with only a single ambiguity. (3) ThePT for finding a single ambiguity in such multiply ambiguous sentences was significantly longer than in singly ambiguous sentences. (4) When one of the interpretations of certain types of ambiguous sentences is less likely than the other (where likeliness is defined in terms of the number of Ss perceiving that inter-pretation first)PT is high. (5) Complexity of the surface and underlying structures (which are defined in transformational grammar) is an important determinant of thePT for surface and underlying structure ambiguities, respectively.     

Development of a Scale of Attitudes Toward School Guidance

This paper reports the development of two alternate forms of a scale for measuring attitudes toward school guidance programs. The resulting instrument features a high degree of usability, since it can be easily self-administered in less than five minutes without the necessity for timing or oral directions. The entire questionnaire appears on a single sheet of paper which the subject also uses to record his responses. Scoring and interpretation are likewise outstandingly simple. Preliminary studies indicate that the scale shows promise of possessing satisfactory technical characteristics.     

Sex Roles, Interpersonal Control, and Depression: Who Can Get Their Way?

This study is one of a series of investigations examining the contribution of sex roles to the development of depression within a learned helplessness framework. Utilizing 143 pairs of undergraduate female participants, the present study explored subjects′ abilities to gain and maintain control in an interpersonal context. Interpersonal control was operationalized as successful persuasion in a two-person discussion task, wherein one participant had hidden instructions to be maximally persuasive in discussing a questionnaire about social behavior. The results indicated that less successful persuasion was associated with increases in depressed mood. Furthermore, women with high masculinity and low femininity were able to gain interpersonal control regardless of the sex role of their partner. The results also suggested that high femininity is associated both with giving up control in interpersonal tasks and with increases in depressed mood when one is faced with the task of exerting interpersonal control. The findings were interpreted in terms of the importance of sex role characteristics in learned helplessness and depression.     

Understanding the language of thought

Conclusions To conclude then, our question was, What determines the content of a thought? This question gets its punch by being set against the background assumption that thoughts are internal physical occurrences. The answer I have proposed is that thoughts can be classified in four importantly different ways. Introspection yields syntactic categories. These are important for cognitive processing, but they do not correspond to contents. A second way of categorizing thoughts is in terms of narrow content. This is determined by the functional role of the thought in rational architecture together with the way in which that rational architecture is tied to the world through input correlations. Narrow contents are indexical, so to get truth bearers we must augment the narrow contents with the values of the indexical parameters. Propositional content can be taken to consist of pairs of narrow contents and values for indexical parameters. Finally, thoughts can be classified in terms of that clauses. This kind of classification does not uniquely determine propositional content, but describes it in a more general way.     

The predictive validity of teacher nominations: A five-year followup of at-risk youth

The purpose of this study was to examine the predictive validity of a teacher nomination procedure for identifying at- risk children. Two hundred and twenty-five children were nominated by their teachers as well- adjusted (n= 75), socially withdrawn (n=76), or socially aggressive (n=74) during the fourth grade. Five years later, 198 of these children (88%) were located and their adjustment evaluated. Significant differences among the nominated children were found on a variety of measures, including academic grades, sociometric status, and social behavior. In addition, differences in school dropout and delinquent offenses were noted. Results are discussed in terms of the validity of teacher nomination procedures and their utility in identifying at- risk youth.     

Semantic and associative priming in the cerebral hemispheres: some words do, some words don't ... sometimes, some places

This study investigated spreading activation for words presented to the left and right hemispheres using an automatic semantic priming paradigm. Three types of semantic relations were used: similar-only (Deer-Pony), associated-only (Bee-Honey), and similar + associated (Doctor-Nurse). Priming of lexical decisions was symmetrical over visual fields for all semantic relations when prime words were centrally presented. However, when primes and targets were lateralized to the same visual field, similar-only priming was greater in the LVF than in the RVF, no priming was obtained for associated-only words, and priming was equivalent over visual fields for similar + associated words. Similar results were found using a naming task. These findings suggest that it is important to lateralize both prime and target information to assess hemisphere-specific spreading activation processes. Further, while spreading activation occurs in either hemisphere for the most highly related words (those related by category membership and association), our findings suggest that automatic access to semantic category relatedness occurs primarily in the right cerebral hemisphere. These results imply a unique role for the right hemisphere in the processing of word meanings. We relate our results to our previous proposal (Burgess & Simpson, 1988a; Chiarello, 1988c) that there is rapid selection of one meaning and suppression of other candidates in the left hemisphere, while activation spreads more diffusely in the right hemisphere. We also outline a new proposal that activation spreads in a different manner for associated words than for words related by semantic similarity.     

A further validation of the bem sex role inventory: A multitrait-multimethod study

The present study used a multitrait-multimethod technique [D.T. Campbell and D. W. Fiske (1959) “Convergent and Discriminant Validation by the Multitrait-Multimethod Matrix,” Psychological Bulletin, 56, 81–105] to examine Bem's [(1974) “The Measurement of Psychological Androgyny,” Journal of Consulting and Clinical Psychology, 42, 152–162] use of an instrumental-expressive dichotomy to conceptualize the Masculinity and Femininity scales of the Bem Sex Role Inventory as statistically orthogonal constructs. Results indicate that while perhaps reliable, masculinity and femininity lack clear convergent and discriminant validity. Therefore, Bem's contention that masculinity and femininity are orthogonal constructs is questioned. Results are discussed in light of trait- vs. method-driven research.     

Training in law and behavioral sciences: Issues from the criminal justice perspective

Interdisciplinary training in behavioral sciences and the law should be appropriate for a criminal justice education program. However, adopting such an interdisciplinary goal is problematic because the divisions in the types of educational curricula need to be confronted. The relationships of the criminal justice academic community with the profession, and of the behavioral sciences with present criminal justice policies, must also be addressed in the attempt to develop familiarity with behavioral sciences and their legal relevance in shaping the criminal justice system. These factors may hinder extensive implementation of such training. Suggestions are made for incorporating this raining in a criminal justice curriculum.
