Comparison of the performances of a fluent and a nonfluent aphasic on a pantomimic referential task

The pantomimic performances of a typical Broca's (nonfluent) and Wernicke's (fluent) aphasic were compared with each other and with four normal control subjects on a simple task of nonverbal referential communication. Both aphasic subjects demonstrated only about 50% accuracy in their pantomimic communication. Also, measures were obtained of the motoric fluency of the pantomimes of all subjects and comparisons were made between the fluent and nonfluent aphasics. These measures demonstrated distinct differences in the fluency patterns of the pantomimes of the two aphasic subjects similar to the differences in speech fluency which distinguish and characterize these two types of aphasia; that is, the fluent aphasic pantomimed fluently and like the control subjects and the nonfluent aphasic pantomimed nonfluently. The quantitative and qualitative similarities in the fluency patterns of the speech and the pantomimic behaviors of the aphasic subjects are discussed in terms of their implications for a definition of aphasia.     

Effects on retroactive of the learned strength of interpolated material

Twelve moderately retarded children were trained on 2-choice visual discrimination problems with interpolation of another item between training and retention tests. The retroactively interfering property of the interpolated items was reduced as it became well-learned. The effect was interpreted to mean that well-learned items are rehearsed less. The results were found to be consistent with predictions from theory.     

The effect of scale modifications on the factorial dimensions and reliability of super's work values inventory

On the basis of previous research findings, 32 new items were added to Super's Work Values Inventory (WVI) and the resulting 77 item instrument was administered to 611 high school sophmores. Guttman's rank-reduction procedure and separate image analyses were employed to examine empirically the effects of additional items on hypothesized item groupings, scale intercorrelations, factorial dimensions, and scale internal consistency reliabilities. Analyses supported the addition of items to the WVI. It was found that the item groupings on the modified instrument were reasonable; the scale intercorrelations and factorial dimensions of both versions were highly comparable; the addition of items had increased the scale internal consistency reliabilities. Comments were made regarding counselors' use of the WVI.     

Affect and delay of gratification

Three experiments investigated the influence of positive and negative affect manipulations on children's preferences for small immediate versus large delayed rewards. Positive and negative affect were induced via verbal instructions to imagine happy and sad experiences. Elementary school children were randomly assigned to a control condition or to one of several treatment conditions consisting of two affect manipulations: a positive followed by a negative, the reverse, and (in the third experiment) two positives or two negatives. In some conditions (in the second and third experiments) measurement of delayed reward preference followed the first and second affect inductions whereas in other conditions (in the second and third experiments) measurement followed only the second affect manipulation. As predicted, negative affect subjects chose fewer large delayed rewards than did positive affect subjects during the first assessment (p < .02). At the second assessment, comparison among treatment and control conditions revealed the influence of a prior commitment effect which negated the potential influence of a second affect manipulation on preference for delayed rewards.     

Extending Holland's theory to adult women

The potential of Holland's theory for use in the vocational guidance of adult women depends in part on more validity data with regard to the conceptual meaningfulness of the constructs. This study reports the findings of a correlative analysis between scores on Holland's Vocational Preference Inventory (VPI), which measures the six “styles”, and selected scales on four criterion tests predicted in advance to be related to the VPI. The findings for this sample of adult women indicate strong evidence for the validity of the Intellectual, Conventional and Enterprising “styles”, but questions are raised with regard to the meaningfulness of the Realistic, Social, and Artistic types.     

The effectiveness of reward and punishment contingencies on response inhibition

The relative effectiveness of reward and punishment on the development of response inhibition was evaluated developmentally. Forty kindergarten and forty second-graders received response inhibition training with half of each group rewarded for inhibiting and half punished for not inhibiting. Reward involved the presentation of positive reinforcers, whereas punishment involved their removal. Punishment produced more inhibition at both age levels than did reward. Transfer of inhibition training was evaluated in two tasks. Transfer effects were observed only on one of the two tasks. Reinforcement contingencies and age did not differentially influence the magnitude of transfer.     

Affective state and preference for immediate versus delayed reward

Fifty-two 9-year-olds were randomly assigned to success and failure treatment conditions involving acceptance or rejection of a drawing made for an art show. In a pilot study, this treatment was shown to influence significantly subjects' affective states. Just after treatment, subjects were presented with choices between pairs of small immediate and large delayed rewards. As predicted, subjects who had experienced success chose more often the large delayed reward than those who failed (p < .02). Prior expectancy for success and sex were not significantly related to choice behavior. The influence of affective state on various parameters of the choice paradigm was discussed, and other evidence was cited indicating that affective state is a major determinant of self-gratification behavior.     

Attention to components or compounds as a factor in discrimination transfer performance.

Prior to being tested with standard reversal or extradimensional (ED) shift procedures, two groups of mentally retarded subjects (MA: 4 to years) were pretrained using two different methods. The Component group received two problems which could be solved easily only by attending to the form components. The Compound group was trained on two problems requiring attention to compound color-form cues. It was assumed that the two solution modes would carry over to the third problem, which was for both groups a standard form discrimination with color variable and irrelevant within settings. The fourth problem was either an ED shift or a reversal. The Component group learned reversal faster than ED shift whereas the opposite was true for the Compound group. Subproblem analyses of ED shift performance showed dependent settings for the Component group and independent settings for the Compound group. Results are consistent with the view that compound and component solutions of discriminative problems are achieved by attention to the abstract dimensions of compounds or components and that attention to either of these dimensions can be trained at higher or lower developmental levels even though the salience of the compound dimension may be initially greater for lower level subjects.     

Coding strategies and cerebral laterality effects

In a short-term recognition memory task, Ss were given relational imagery and rehearsal coding strategies in different sessions, with probes presented to the left or right cerebral hemisphere. Consistent with a model of separate processing systems for verbally and visually coded information, Ss yielded significantly faster response latencies for probes to the left hemisphere than the right when employing the rehearsal strategy, and significantly faster latencies for probes to the right hemisphere than the left when using the imagery code. This suggests that cerebral laterality effects are functionally related to coding strategies, and argues for the inclusion of imagery, or generated visual information, as part of the visual processing system. As such, generated visual information may be viewed as a coding alternative to verbal mediation.     

A neural activity interpretation of luminance effects on infant pattern preferences

Visual pattern preferences were established for 9- and 13-week-old infants (N = 96) using stimuli varying in contour density presented either at a low, moderate, or high luminance level. Age differences in the maximally preferred patterns across stimuli and luminance levels indicated that luminance interacts with contour density in determining stimulus preference functions for a given age. A neural activation model based on synchronous neural activity was advanced to describe these results.     

Measuring a macho personality constellation

A Hypermasculinity Inventory was developed to measure a macho personality constellation consisting of three components: (a) calloused sex attitudes toward women, (b) violence as manly, and (c) danger as exciting. The 30 forced-choice items were selected by a two-stage internal consistency item analysis. Issues of substantive and structural validity were addressed by considering item content, test format, homogeneity of items, and the factor structure of items. The Cronbach α coefficient for the Hypermasculinity Inventory was .89 in the present sample of 135 college men. External validity was assessed by correlating scores of the Hypermasculinity Inventory with self-reported drug use, r(135) = .26, p < .01, aggressive behavior r(135) = .65, p < .001, and dangerous driving, r(136) = .47, p < .001, following alcohol consumption, and delinquent behavior during the high school years, r(135) = .38, p < .01. Construct validity was supported further by a pattern of theoretically meaningful correlations with the Personality Research Form (D. N. Jackson, 1974, Goshen, NY: Research Psychologists Press). The discussion considered further research that is needed to adduce additional evidence for the construct validity of the Hypermasculinity Inventory as a measure of the macho personality pattern.     

Reacting to reactance: An Interpersonal interpretation of the need for freedom

This study was designed to investigate the conditions under which the negative consequences of social influence attempts can be mitigated by freedom-affirming interventions. Eighty-eight high school girls received an influence message, presumably written by a co-worker, containing either a threat or a promise. In addition, subjects were or were not given a choice option as to mode of compliance, if they chose to comply with the message. In half the cases, the Interpersonal condition, subjects received their choice/no choice option from their co-worker; in the other half of the cases, the Noninterpersonal condition, subjects were assigned the choice/no choice option by a random event unknown to the influencing agent. As anticipated, in the Interpersonal as compared to the Noninterpersonal condition, (a) threats produced greater compliance when a choice was offered than when it was not, and (b) promises and threats were more equivalent in gaining compliance when a choice was offered than when it was not. These results, which suggest that in a social setting individuals' concerns about freedom are interpersonally motivated, are discussed in terms of their relation to and implications for reactance theory.     

Metaphoric comprehension: Studies in reminding and resembling

The theoretical problems posed by metaphoric comprehension are discussed in the context of experiments on prompted recall. Listeners heard sentences of the form “Topic is (like) Vehicle.” In most cases, a statement of the implicit resemblance (the “ground”) was very effective in prompting recall of its related metaphor. This result could not be attributed to the activation, transfer, or additive combination of pre-existing properties of the topic and vehicle terms or to pre-existing associations between grounds and sentence terms. It is argued that the vehicle domain guides a novel schematization of the topic domain, that the perceived resemblance is a higher-order relation among entities (both explicit and implicit) in each domain, and that this abstract relation constitutes the “functional memory unit.” Prompted recall may begin with recognition of this previously experienced relation.     

The sausage machine: A new two-stage parsing model

It is proposed that the human sentence parsing device assigns phrase structure to word strings in two steps. The first stage parser assigns lexical and phrasal nodes to substrings of roughly six words. The second stage parser then adds higher nodes to link these phrasal packages together into a complete phrase marker.This model of the parser is compared with ATN models, and with the two-stage models of Kimball (1973) and Fodor, Bever and Garrett (1974). Our assumption that the units which are shunted from the first stage to the second stage are defined by their length, rather than by their syntactic type, explains the effects of constituent length on perceptual complexity in center embedded sentences and in sentences of the kind that fall under Kimball's principle of Right Association. The particular division of labor between the two parsing units allows us to explain, without appeal to any ad hoc parsing strategies, why the parser makes certain ‘shortsighted’ errors even though, in general, it is able to make intelligent use of all the information that is available to it.     

Determinants of spelling ability in deaf and hearing adults: Access to linguistic structure

The extent to which ability to access linguistic regularities of the orthography is dependent on spoken language was investigated in a two-part spelling test administered to both hearing and profoundly deaf college students. The spelling test examined ability to spell words varying in the degree to which their correct orthographic representation could be derived from the linguistic structure of English. Both groups of subjects were found to be sensitive to the underlying regularities of the orthography as indicated by greater accuracy on linguistically-derivable words than on irregular words. Comparison of accuracy on a production task and on a multiple-choice recognition task showed that the performance of both deaf and hearing subjects benefited from the recognition format, but especially so in the spelling of irregular words. Differences in the underlying spelling process for deaf and hearing spellers were revealed in an analysis of their misspellings: Deaf subjects produced fewer phonetically accurate misspellings than did the hearing subjects. Nonetheless, the deaf spellers tended to observe the formational constraints of English phonology and morphology in their misspellings. Together, these results suggest that deaf subjects are able to develop an appreciation for the structural properties of the orthography, but that their spelling may be guided by an accurate representation of the phonetic structure of words to a lesser degree than it is for hearing spellers.     

Effect of donor resources on recipient self-esteem and self-help

A 2 (aid vs no aid) × 2 (high vs low resource potential donor) between subjects design tested the effects of aid and donor resources on recipient self-perceptions and subsequent self-help behavior. The results were characterized by interactions between the two factors. Subjects who received aid from a low resource donor perceived themselves more positively and engaged in less self-help than subjects in the no-aid low resource potential donor condition. In contrast, subjects who received aid from a high resource donor perceived themselves less positively and tended to engage in more self-help behavior than subjects in the no-aid high resource potential donor condition. The relationship between threat to self-esteem inherent in aid and subsequent self-help is discussed in terms of self-esteem theory.
