A study of spelling in aphasia

To secure systematic information on spelling abilities following damage to the dominant hemisphere, a test probing performance in three modalities of response was administered to a group of aphasic patients. Except for a predictable deficit among anterior aphasics in oral spelling, anterior and posterior aphasics exhibited comparable performances on the measures of spelling. However, anterior and posterior aphasics differed from one another on the kinds of words they most accurately spelled, the errors they were prone to make, and certain strategies which they characteristically adopted. These results suggest two alternative approaches to spelling: one approach, common in posterior aphasics, entails choosing letter combinations on the basis of their customary sounds; a second approach, common among anterior aphasics, appears to rely on a partially preserved image of the word's appearance.     

Idioms in sentences: Effects of frequency,literalness, and familiarity

This study investigated the relationship between subjective frequency of literal usage (literalness), subjective frequency of figurative usage (familiarity), and mean Kucera and Francis (1967) word frequency for idiom phrases. Kucera and Francis frequency was found to be independent of both familiarity and literalness. Furthermore, it was found that literalness, but not the Kucera and Francis frequency of the words in the phrase, affected reading time for literal uses of idioms. For figurative uses of idioms, familiarity and written frequency interacted. A model of idiom processing consistent with the current results and previous results is proposed. In addition, subjective familiarity and literalness norms are provided for 245 idioms.Portions of the normative study were based upon subjects in Schweigert and Cronk (1992).     

Humanizing education in the Soviet Union: A plea for caution in these postmodern times

In this article, the author problematizes the process of humanizing education in the era of perestroika and glasnost. Identifying herself as a democratic socialist, Kohli invites her Soviet colleagues to acknowledge the criticisms of liberal capitalism before they move headlong in that direction. In deconstructing such taken-for-granted concepts as individualism, democracy, market economy, and community, Kohli suggests that both the West and the East could benefit from re-visiting their respective revolutionary traditions at this crucial historical time.     

Escalating schedules of incentives increase physical activity with no differences between deposit and no-deposit groups: A systematic replication

Physical inactivity has increasingly affected public health in the United States during the COVID-19 pandemic as it is associated with chronic diseases such as arthritis, cancer, and heart disease. Contingency management has been shown to increase physical activity. Therefore, the present study sought to evaluate the effects of an escalating schedule of monetary reinforcement with a reset contingency on physical activity, as compared between 2 counterbalanced groups in which a monetary deposit of $25 was either required (deposit group) or not (no-deposit group). Twenty-five adults wore Fitbit accelerometers to monitor step counts. An ABA reversal design was used; in the 2 baseline phases, no programmed contingencies were in place for step counts. During intervention, step goals were set using a modified 70^th percentile schedule with a 7-day window: Reaching the first goal would result in $0.25, and incentives increased by $0.25 for each subsequent day in which the goal was met. Failure to reach a goal resulted in a reset of the monetary incentive value to $0.25. Ten out of 12 participants from the deposit group were determined to be responders to intervention, whereas 8 out of 13 participants from the no-deposit group were determined to be responders to intervention. Overall, there were no significant differences between the groups' step counts. However, the deposit group's intervention was cheaper to implement, which suggests that deposit contracts are a viable modification for physical activity interventions.     

Conversations on clinical supervision: benefits perceived by school counsellors

This Australian study describes the benefits of clinical supervision as perceived by school guidance officers who work in a large education authority. The participants were a random sample of guidance officers and senior guidance officers who agreed to participate in focus group interviews conducted via teleconference calls. The benefits of and reasons for clinical supervision graphically described by the participants raise questions about the cost of inadequate supervision to the individual counsellors themselves and to the profession as a whole. The findings become even more important when considered in light of the world of work of the 21st century.     

The Role of Expectations in Effective Genetic Counseling

The goals for this investigation were to assess individuals' expectations for social support from genetic counselors, and to explore how these expectations influence perceptions of genetic counselor effectiveness. Two studies were conducted to address these goals. Results from the first study show that individuals most frequently expect genetic counselors to provide options and support following the disclosure of distressing test results, while data from the second study demonstrate that expectations play a significant role in individuals' assessment of genetic counselor effectiveness. These findings shed light on what individuals expect from genetic counselors following the disclosure of medically positive test results and inform how these expectations influence the success of genetic counseling sessions.     

Male HIV-1 transgenic rats show reduced cocaine-maintained lever-pressing compared to F344 wildtype rats despite similar baseline locomotion

The HIV-1 transgenic (Tg) rat model is valuable for understanding HIV-associated neurocognitive disorders (HAND) and accompanying substance use and misuse. Tg and F344/NHsd wildtype (WT) rats were allowed to self-administer intrajugular cocaine. For the first 7 sessions, neither genotype self-administered cocaine (0.1 mg/kg/infusion) on a fixed ratio 1 schedule. We thus implemented a lever–cocaine “autoshaping” session followed by a series of manipulations changing dose and reinforcement schedule. Tg rats self-administered much less cocaine than WT rats throughout the study. Of 8 Tg rats, 5 modestly increased self-administration from sessions 36–50. Of those, only 3 showed a lever discrimination. Of 10 WT rats, 8 acquired robust self-administration by session 19; all WT rats self-administered cocaine by the end of the study. WT and Tg rats had similar baseline locomotor activity in the self-administration chamber suggesting that the low levels of cocaine intake in the Tg rats did not reflect a nonspecific motor impairment in this rat strain. Concomitant measurement of activity with self-administration revealed activity increases that followed increased cocaine intake. That relation held in Tg rats. Therefore, the present study provides evidence that HIV-1 Tg rats are less sensitive to the reinforcing effects of cocaine than their F344 WT counterparts.     

Maternal correlates of stability and change in infant-mother attachment

The relations between maternal control style, sensitivity, and childrearing attitudes on one hand and the stability of the infant-mother attachment relationship on the other were examined in a sample of 38 mother-infant dyads. The mother-child pairs were observed during a structured play session and in Ainsworth's Strange Situation when the infants were 12 and 20 months old, a developmental period characterized by increased autonomous functioning. Our results suggested that infants whose mothers had nonpunitive childrearing attitudes, were sensitive, and supportive of their infants' striving toward autonomy remained, or became, secure in their attachment relationship over their second year of life. Mothers who were more punitive, more controlling, and less sensitive had infants who either remained or became insecurely attached across this developmental period. While previous research has linked attachment stability to socioeconomic factors, the present investigation points to the importance of more subtle interactive variables to the understanding of the attachment relationship.
