Multidimensional assessment of depression

A brief version of the Multiscore Depression Inventory was evaluated. Good coefficient alpha and test-retest reliabilities were obtained for the total score and the subscales. Two factor analyses were reported which appear to justify the use of a multiscore approach for at least 8 of the 9 subscales: helplessness, energy level, guilt, social introversion, cognitive difficulty, irritability, pessimism, and low self-esteem. Sad mood apparently overlapped with energy level on one analysis (replicating findings with the 118-item Multiscore Depression Inventory), and with self-esteem on the second analysis. Normative data are provided on diverse samples totaling 849 subjects.     

Animal research in psychology: declining or thriving?

From Dialog's PsychINFO database the number of studies with 6 species reported in the Psychological Abstracts was calculated for each year from 1967 to 1988. Also, the number of studies with an additional 11 species were calculated for each year from 1973 to 1988. A hand search in the Journal of the Experimental Analysis of Behavior and Learning and Motivation was also conducted to explore trends in studies on 12 species from 1970 to 1987. The numbers of studies on many species (e.g., baboons, bats, chimpanzees, dolphins, gerbils, guinea pigs, gorillas, hamsters, lemurs, mice, pigeons, rats, seals, and snakes) have remained stable. There has, however, been a steady decline in the numbers of studies on selected species (e.g., cats, dogs, and rabbits). Possible reasons for changing trends in studies on selected species include: increased costs, the cognitive emphasis in psychology, and arguably, animal rights activism.     

Quantitative analysis of aphasic sentence production: further development and new data

The narrative production of patients with Broca's aphasia and age-and education-matched control subjects was analyzed using the Quantitative Production Analysis (Saffran et al., 1989), a procedure designed to provide measures of morphological and structural characteristics of aphasic production. In addition to providing data for a larger number of subjects than in the original study, we provide data on interrater and test-retest reliability. The data were also submitted to factor and cluster analyses. Two factors characterized the data and the cluster analysis yielded four sets of patients who performed differently on these factors. In particular, there is evidence that agrammatic patients can differ in their production of free and bound grammatical morphemes, substantiating earlier claims in the literature.     

Agrammatic Broca's aphasia is not associated with a single pattern of comprehension performance

One influential hypothesis posits that the brain regions implicated in Broca's aphasia are responsible for specific syntactic operations that are necessary for the comprehension and production of sentences (Grodzinsky, 1986, 1990, in press). The empirical basis of this hypothesis is the claim that Broca's aphasics have no difficulty understanding sentences in the active voice (and other "canonical" sentence types, such as subject relatives and clefts with negative predicates), but perform at chance level with passive voice constructions (and other "noncanonical" sentences such as object-gap relatives and object clefts). In the face of well-established results indicating that Broca's aphasics can exhibit several different performance patterns on these sentence types, Grodzinsky, Pi?ango, Zurif, and Drai (1999) argued that these conflicting results do not challenge the theory when the data are analyzed appropriately. They carried out a creative statistical analysis of the comprehension performance of published cases of Broca's aphasia and concluded that all of these cases are in agreement with the predicted pattern: chance on passives and 100% correct on actives. Here we show that the statistical reasoning adopted by Grodzinsky et al. (1999) is flawed. We also show that the comprehension performance of a substantial number of the Broca's aphasics in their own sample does not conform to the pattern required. Rather, contrary to these authors' claim, Broca's aphasia is not associated with a consistent pattern of sentence comprehension performance, but allows for a number of distinct patterns in different patients.     

How "regular" is sentence comprehension in Broca's aphasia? It depends on how you select the patients

Grodzinsky, Pi?ango, Zurif, and Drai (1999) argue that a statistical analysis of pooled sentence comprehension data from published studies of Broca's aphasic patients supports the dominance of a differential pattern of performance on active and passive voice structures. They argue that these results counter a previous study in which individual patient data from published studies were analyzed. However, Grodzinsky et al. have not carried out a true test of their hypothesis, but have biased the outcome by selecting samples for analysis that support their claims.     

Importance of fathers' parenting to African-American toddler's social and cognitive development

The present study examined the degree to which parenting attitudes and behavior (i.e., self-reported warmth, restrictiveness, and behavioral sensitivity as assessed during a freeplay session) were related to toddlers' development. Results showed a restrictive attitude was negatively related to social and cognitive development, whereas paternal sensitivity was positively related to aspects of social development that are less dependent on language skills (e.g., motor and daily living skills). Fathers of girls exhibited greater sensitivity in their freeplay interactions than fathers of boys. More globally, the present research demonstrates important relations between the parenting attitudes and behavior of low- to working-income African-American fathers and young children's development, and similarities to White, middle-income fathers.     

Conscious and Preconscious Uses of Memory in Patients with Depressive and Somatoform Disorders

This study investigated whether conscious and preconscious memory features contribute to discrimination between depressive and somatoform disorders. Thirty-one participants fulfilling the diagnostic criteria for a somatoform disorder and 28 participants fulfilling the criteria for depression were examined within the framework of the process–dissociation paradigm using neutral, health-threatening, and general threatening words in a lexical decision task. Parameters of conscious memory, preconscious memory, and chance were used to compare memory features of both the groups. There was an inverse relationship between conscious and preconscious memory effects for health-threatening stimuli in the group of patients with somatoform disorders but not in the group of depressive patients. Patients with somatoform disorders showed a significantly lower level of conscious memory for health-threatening stimuli than depressive participants. Compared to depressive patients, a more dynamic relationship between decreased conscious and increased preconscious memory for health-related stimuli seems to be characteristic for patients with somatoform disorders.
