Semantic mechanisms in paralexia

This study explores the effects of semantic constraints on the occurrence of paralexic responses in two patients who tend to produce semantic errors in reading aloud. In the first experiment, semantic constraints were provided by using words as proper names (e.g., “brown” vs. “Sam Brown”), and in the second by using short, highly familiar phrases to restrict the meaning of the target word (e.g., the polar bear; green with envy). These constraints were found to be effective in reducing the frequency of paralexic errors.     

Maintaining disulfiram ingestion among outpatient alcoholics: a security-deposit contingency contracting procedure

Disulfiram is frequently prescribed to alcoholic patients as a deterrent to drinking. Although ingestion of ethanol by a disulfiram patient quickly results in an intense dysphonc reaction, the drug is not generally credited with significant value in alcoholism treatment (Mottin, 1973). It is suggested that most alcoholics simply stop taking the medication (Gerrein et al., 1973). and review articles conclude that motivation for abstinence is the crucial variable involved in successful disulfiram treatment (Ditman, 1966: Mottin, 1973).Motivation may be a characteristic of environmental contingencies rather than of individuals. If so, environmental contingencies should permit one to design into a disulfiram treatment progrim the requisite motivation to achieve therapeutic success. Contingency management procedures supporting disulfiram ingestion reported to date (Liebson et al., 1973: Haynes, 1973) have been of the sort to be imposed upon difficult populations rather than offered to general treatment applicants. Contingency contracting may represent a technique for supporting disulfiram ingestion appropriate to the broader general population of voluntary alcoholism treatment applicants. Contingency contract treatment (Homme, 1969; Stuart, 1971) is a procedure in which client and therapist mutually agree to establish an incentive for the client to achieve a behavioral goal. Contingency contracts can be viewed as a form of self-control therapy, and have been applied in a wide variety of problem areas, including school problems (Homme, 1969: Cantrell, et al., 1969). delinquency (Stuart, 1971),weight control (Mann, 1972). smoking reduction (Elliott and Tighe, 1968: Winett, 1973), drug abuse (Boudin, 1972), and alcoholism (Miller, 1972).Frequently contingency contracting involves the client's posting of a financial security deposit to serve as his incentive for achieving the agreed-upon therapeutic goal (Tighe and Elliot, 1968). This security deposit can be earned back consequent upon achieving specific goals, or sacrificed consequent upon failure. Controlled studies by Mann (1972) and by Winett (1973) have demonstrated this security-deposit procedure to be effective in enhancing weight loss and smoking reduction, respectively.We report here on our experience with application of the security deposit contracting procedure to maintaining routine disulfiram ingestion among outpatients in an alcoholism treatment program.     

Scrutinizing application: An agenda for applied developmental psychology

This paper dissects two views of application. The first is associated with an ontogenetic, general skills perspective which assumes that applications involve bringing to bear general concepts and principles on practical problems, deviant populations and the match between developing individuals and the environment they inhabit and use. However, that ontogenetic view and its associated applications may be flawed. A second functionalist view of application is described which suggests a need to examine the meaning of application and the contexts where applications are appropriate. Two questions might profitably be evaluated simultaneously: How does the developing individual gain access to relevant competencies and adapt them to new circumstances?, and How does the developmentalist decide what is relevant and usable for practice? A particular developmental curriculum fitting these views is described.     

Motivation to manage among college business students: A reassessment

The present study reassesses trends in motivation to manage among college business students (N = 216). Motivation to manage scores are compared with J. B. Miner's (Personnel Psychology, 1974, 27, 605–613) results for three periods since the early 1960s, across two types of universities—public and private, and between males and females. Results indicate that the downward trend in motivation to manage scores appears to be reversing; business students at the private university scored higher on motivation to manage than those at the public university, and males scored higher than females. Implications for vocational research are discussed.     

Semantic processing can facilitate free recall in mildly retarded adolescents

The efficacy of semantic processing in free recall was investigated in two experiments with EMR adolescents. In Experiment 1, they were taught to use one of two semantic strategies for memorizing a 15-word list. Compared with controls, neither strategy helped recall either in original learning or transfer. In Experiment 2, one of the semantic strategies, a story mnemonic, was investigated further. Rather than being taught to construct their own stories as in Experiment 1, subjects in Experiment 2 were provided with experimenter-composed stories. They showed better immediate recall and retention after 2 months than did no-strategy controls. However, about 1 year after original learning, the retention of experimental and control subjects no longer differed. Discussion focused on the story mnemonic's potential utility and the criteria for judging such potential, e.g., amount of facilitation, ease of training and performance of the strategy, and the degree of its generalizability.     

Parallel function strategy in pronoun assignment

Subjects completed sentences of the form NP1 aux V NP2 because (but) Pro … (e.g., John may scold Bill because he …) with a reason or motive for the action described. A basic perceptual strategy was hypothesized to underlie the comprehension of these sentences which have a potentially ambiguous pronoun in the subject position of the subordinate clause. It was expected that listeners would interpret the pronoun as being coreferential with the subject NP of the main clause, the NP with the same grammatical function. While this strategy accounted for the major share of the results, semantic factors restricted its use, establishing an interpretation in which the pronoun was coreferential with the object NP of the main clause.     

Impairment of auditory perception and language comprehension in dysphasia

Men with chronic focal brain wounds were examined for their ability to discriminate complex tones, synthesized steady-state vowels, and synthesized consonant—vowel syllables. Subjects with left hemisphere damage, but not right hemisphere damage, were impaired in their ability to respond correctly to rapidly changing acoustic stimuli, regardless of whether stimuli were verbal or nonverbal. The degree of impairment in auditory processing correlated highly with the degree of language comprehension impairment. The pattern of impairment of the group with left hemisphere damage on these perceptual tests was similar to that found in children with developmental language disorders.     

Extraversion and neuroticism in orienting reflex dishabituation

The present study examined the effects of extraversion (E) and neuroticism (N) as individual difference dimensions and of stimulus intensity on electrodermal orienting response habituation, test response, and dishabituation. Subjects were 162 college students selected from a screening sample of 860 as representing extreme groups of high, medium, and low E crossing with high, medium, and low N. Subjects in all nine resulting groups were habituated to criterion on auditory stimuli of 60, 80, and 100 db. A novel (test) stimulus and a dishabituating standard stimulus followed criteron habituation at each intensity. Results indicated that response amplitude for initial, test, and dishabituation responses was a direct function and that habituation rate (trials-to-criterion) was an inverse function of stimulus intensity. Extraverts habituated more rapidly than introverts at high intensity and gave smaller test and dishabituation responses. Some results differed when regression coefficients defined habituation rate and when first stimulus intensities alone were examined. Correlations among initial, test, and dishabituation responses and between each of these and the two measures of habituation rate are also reported. Results were interpreted as partially supportive of Eysenck's theory.     

Naming in aphasia: Interacting effects of form and function

The naming difficulties of Broca's and anomic aphasics were explored in relation to a recently developed model of the normal mental lexicon which stresses the importance of integrating perceptual and functional information in the act of naming, and equally stresses the inherent vagueness of conceptual categories based on such information. Subjects were shown line drawings of various food containers varying in physical features such as height and width; they were required to select a name for the object from a multiple choice list (cup, bowl, or glass). Prototypical as well as nonprototypical objects were shown. The Broca's aphasics showed relatively normal naming profiles. In contrast, the posterior patients were unable to integrate perceptual and functional information and were insensitive to the fuzzy boundaries between conceptual categories. The results obtained for the posterior patients are interpreted as reflecting an impairment in the underlying conceptual organization of the lexicon rather than retrieval difficulties.
