On multiple determinants of racial differences in intelligence: A reply to Jensen

A belief in the multidimensional nature of intelligence prompted Borkowski and Krause (1983) to reexamine the race-IQ controversy from a new theoretical perspective. Jensen has subsequently forced us to look more carefully at data presented in the earlier paper. After we corrected all measures in the perceptual efficiency and executive systems for unreliability and rethought the earlier data, our original conclusions remain tenable: Control processes and metacognitive states are important factors in understanding the sources of race-related differences in intelligence. In accord with the earlier conclusion, we do not deny the association of “speediness” (perceptual efficiency) with race-IQ differences but rather argue for the necessity, and utility, of a broader, multidimensional conceptualization of the nature and growth of intelligence.     

Confrontation naming impairment in dementia

In tone languages pitch variations (tones) serve to distinguish the lexical meanings of words. This study was conducted to examine the extent and nature of impairment in the perception of tones by aphasic patients who were monolingual speakers of Thai, a tone language which has five contrastive tones (mid, low, falling, high, rising). Six subjects participated in the study: two Broca aphasics, one transcortical motor aphasic, one conduction aphasic, one right brain-damaged nonaphasic, and one normal control. Three sets of stimuli (two real-speech, one synthetic-speech) were presented for identification, each set containing five Thai words minimally distinguished by tone. Results of the perception tests indicated that the performance of all four left brain-damaged aphasics differed significantly from that of the normal control, while the performance of the right brain-damaged nonaphasic did not. The normal performance of the right brain-damaged nonaphasic patient on this tone identification task suggests that deficits in the perception of tone exhibited by left brain-damaged patients can be attributed specifically to pathology in the language dominant hemisphere rather than to a general brain-damage effect. No difference in performance among the left brain-damaged patients could be attributed to a specific type of aphasic syndrome. The pattern of tonal confusions of the aphasics in comparison to that of normals suggests that their deficit is primarily quantitative rather than qualitative. Although two (mid, low) of the five tones accounted for a large percentage of the aphasics' errors, no uniform rank order of tones in terms of identifiability could be established across aphasic subjects, which suggests that their deficit is general to all five tones rather than selective to individual tones.     

Silent reading: Insights from second-generation deaf readers

Previous studies indicate that hearing readers sometimes convert printed text into a phonological form during silent reading. The experiments reported here investigated whether second-generation congenitally deaf readers use any analogous recoding strategy. Fourteen congenitally and profoundly deaf adults who were native signers of American Sign Language (ASL) served as subjects. Fourteen hearing people of comparable reading levels were control subjects. These subjects participated in four experiments that tested for the possibilities of (a) recoding into articulation, (b) recoding into fingerspelling, (c) recoding into ASL, or (d) no recoding at all. The experiments employed paradigms analogous to those previously used to test for phonological recoding in hearing populations. Interviews with the deaf subjects provided supplementary information about their reading strategies. The results suggest that these deaf subjects as a group do not recode into articulation or fingerspelling, but do recode into sign.     

Bound morpheme loss errors in normal and agrammatic speech: One mechanism or two?

Loss errors involving bound morphemes in normal and agrammatic speech are examined to determine if all errors can be due to a single processing problem. It is concluded that two problems are present. First, there is a general problem with accessing bound morphemes (or forms containing bound morphemes), leading to the production of the base form. Second, there is a syntactic problem involving agreement. In agrammatism, the first problem is differentially exacerbated. Implications for normal and agrammatic speech are examined.

Prosodic disturbance in aphasia: Vowel length in Thai

The aim of this study is to determine to what extent a phonologically contrastive function of the prosodic feature of length is resistant to impairment in aphasia. The language chosen for investigation is Thai, a language which contrasts short and long vowels. Subjects included two Broca aphasics, one transcortical motor aphasic, one Wernicke aphasic, one conduction aphasic, one nonaphasic right-brain-damaged patient, one nonaphasic cerebellar dysarthric patient, and five normal controls. The subjects read a list of words containing short and long vowels. Vowel durations were measured from spectrograms. The results showed that the timing of vowel duration for signaling the contrast between short and long vowels remains relatively intact in nonfluent as well as fluent aphasic patients. These data are brought to bear on issues concerning the specialization of the left hemisphere for temporal processing, the contribution of the right hemisphere to the processing of nonaffective components of prosody, the nature of prosodic disturbance in Broca's aphasia and cerebellar dysarthria, and the separate disruption of prosodic features.     

Empathetic perception of emotional displays in films as a function of hedonic and excitatory state prior to exposure

A film clip depicting a young couple in a dysphoric encounter was seen following one of four film segments that were selected and pretested to effect a factorial variation in (a) hedonic tone (positive, negative) and (b) excitatory potential (low, high). Reactions to the subsequent film were assessed via ratings to test predictions from excitation-transfer theory and to determine sequential effects in hedonically valued experiences. In a first experiment, in which the subsequent film was viewed immediately after the antecedent film, a nearly significant distraction effect of excitation occurred, that is, affective responses to the subsequent film were less intense following high-excitation films than following low-excitation films. In a second experiment, in which the procedure employed in the interval between films was changed to foster close attention to the subsequent film, an excitation-transfer effect was observed, with the dysphoric encounter being perceived as sadder after high-excitation films than after low-excitation films. In both experiments, hedonic-set effects were also observed. The role of cognitive adjustment in excitation transfer was discussed.     

Anxiety and aggression of high and low assertive persons following conflict

This experiment examined changes in anxiety and differences in aggression for high and low assertive women when different degrees of conflict were encountered. As predicted, low assertive women were intially more uneasy or anxious than high assertive women when they were placed in a conflictual situation. When the level of actual conflict was low, the level of anxiety of low assertive women decreased. However, when the actual level of conflict was high the anxiety level of low assertive women remained unchanged. These results were taken as support for the fear of conflict hypothesis which predicted that the reduction in anxiety for low assertive persons is contingent upon whether or not the anticipated conflict is actually encountered. The results also indicated that high assertive women were not significantly more aggressive than low assertive women. This finding provided support for Galassi's position that assertiveness and aggression are distinct concepts.     

Contrast effects and their relationship to subsequent behavior

The present study attempted to apply social judgment theories to the effects of context on judgments of the importance of a social issue and on subsequent issue-related behavior. Subjects judged the importance of a target issue (recycling) in the context of either important or unimportant social issues and were subsequently asked in a separate setting for help on a local recycling project. Context produced contrast effects on rating scale judgments of the importance of recycling. These judgments, if salient, were then used as a basis for subsequent support of the recycling project. When either the initial judgment was not salient or no prior judgment of recycling was made, the importance of the context had a positive effect on amount of support for recycling, such that more help was given in the important context conditions. Results indicate that contrast effects on the ratings are response base rather than perceptual in nature, but that the rating, if salient, can serve as subsequent behavior and attitudes.
