Rumination and self-defining memories in the context of health concerns

Individuals with health anxiety report experiencing a strong sense of vulnerability to illness. Such beliefs may be driven by the biased recollection of past illness-related events. However, little research has explored the role of memory in health anxiety. In other disorders, rumination has also been identified as a process that leads individuals to recall memories dominated by the content of their concerns. This study examined the proposition that rumination might impact the content of “self-defining” autobiographical memories among 60 college students with varying health anxiety (35% with clinical-level health anxiety). Participants were randomised to experiential/ruminative self-focus conditions, and then they completed the Self-Defining Memory Task. Responses were coded for valence and illness-relatedness. Results indicated that rumination led participants to retrieve more illness-related self-defining memories, while higher health anxiety scores were associated with more negative, but not more illness-focused memories. Ruminative thinking appears to activate health concerns, and may play a role in maintaining ongoing health anxiety.     

Play and cognition: Studies of pretence play and conservation of quantity

Study 1 examined the relative effectiveness of four different training conditions on the attainment of conversation of quantity. Subjects were 75 nonconserving preschoolers, ranging in age from 3.10 to 5.0 years. Treatment consisted of pretense play training, direct conservation training, a combination of pretense play and conservation training, mere exposure to the conservation tasks without the benefits of instruction, and a control condition which provided only conservation pre- and post-tests. The results of the two conservation post-tests indicated that a combination of pretense play and conservation training was the most effective condition, followed by the conservation training and then by the pretense play training. The data also suggested that the effects of the conservation-only training condition might be less stable than those attained with pretense play training. Study 2 compared the effectiveness of child initiated pretense play training with adult initiated play. Subjects were 47 nonconserving children ranging in age from 4.0 to 5.8. Treatment consisted of child initiated pretense play, adult initiated play, a condition which combined both treatments, and a control group. The results of the two conservation post-tests indicated that the child initiated pretense play training was most effective, followed by the combined condition and by the adult initiated training. The three pretense play training conditions induced significantly more conserving responses in previously nonconserving children than the control group.     

Methodological Problems in Operant Learning Research with Human Infants

A great number of the recent studies on infant operant learning use the mobile conjugate reinforcement paradigm with 2- and 3-month-old infants. This paradigm has proved to be adequate for the study of learning and the transfer of learning. However, difficulties linked to the high attrition rates of subjects, and the variability in performance are frequently observed in studies using other paradigms or in studies with older infants (4–5-month-olds). The problems noted in a group of studies seem to be related to important methodological issues such as the brevity of the learning sessions, the choice of dependent measures, and the management of variability in performance. The use of single-subject designs and the use of variables encountered in infants' daily learning experiences may be the solution to some of the problems.     

Effects of occupational prestige,employment status,and marital status on perceptions of mothers

Perceptions of mothers were investigated as a function of their marital status, employment status and prestige of their jobs. College students (128 females and 96 males) evaluated a briefly described adult female stimulus person on 24 7-point bipolar scales that described job performance characteristics and personality traits. Each subject rated one of 16 mothers of a young child. The mother was portrayed as either divorced or married and as either currently employed or formerly employed (by choice) in an occupation of either moderate or low prestige. Employed mothers were perceived as more competent in their jobs but as less well-adjusted than nonemployed mothers. Mothers with moderate-prestige occupations were viewed as more competent than those in low-prestige occupations, especially if they were currently employed. Married mothers were seen as better adjusted than divorced mothers.Portions of this paper were presented at the meeting of the Midwestern Psychological Association, Chicago, Illinois, May 1989.     

Potential for personhood: A measure of life the severely defective newborn,legal implications of a social-medical dilemma

This paper asks for legislation that will remove criminal sanctions from good faith decisions by parents and physicians to allow severely defective newborns to die. In so doing it attempts to bring to satisfactory resolution conflicting points of view in the disciplines of moral philosophy, medicine, and law. This paper argues that euthanasia of severely defective newborns is morally justifiable and legally permissible within reasonable extensions of current interpretations of the Federal Constitution by the Supreme Court. It describes the medical dilemma, evaluates the moral issues involved, and delineates possible legal alternatives.     

Effect of noise distractibility on the spans of apprehension of hyperactive boys

Denton and McIntyre (1978), using a forced-choice letterrecognition procedure, demonstrated increasing reductions in the spans of apprehension of hyperactive as compared to normal boys when a signal letter was embedded within an increasing number of noise letters. In the present study, the effect of variations in the amount of physical signal-noise similarity and noise redundancy upon the spans of apprehension of hyperactive and normal boys was compared to determine whether noise letters act as more potent distractors for the hyperactive boys. Results indicated the spans of both groups were effected equivalently by variations in signal-noise similarity and noise redundancy. No evidence for a distractibility explanation was obtained.     

A North American perspective on the psychological maltreatment of children

Psychological maltreatment may be the most common form of abuse suffered by North American children within the family environment. However, little effort has been directed towards eliminating and preventing it. The present article emphasizes the importance of thoroughly understanding the phenomenon so that effective intervention strategies can be developed. North American research studies of child maltreatment are reviewed and discussed with particular emphasis placed upon the manifestations of psychological maltreatment, the scope and the consequences of the problem, and the identification of associated risk factors. The paper identifies several areas for improvement before successful interventions can be conceptualized.     

The functions of phonology in the acquisition of reading: Lexical and sentence processing

It has been claimed (V. Coltheart, Laxon, Rickard, & Elton, 1988) that learners as well as skilled readers use phonology for multiple functions in reading-for-meaning tasks. This claim was examined using lexical decision and sentence evaluation tasks. It was found in the first experiment that the type of instruction learners had received determined whether there was prelexical use of phonology in responding to items out of sentence context. Type of instruction had no effect when the items were in context. In the second experiment, performances on a homophone sentence evaluation task and a homophone semantic decision task, which excluded sentence processing, were examined. The results suggest that phonology served the function of access to lexical meanings in addition to any function in postlexical sentence processing. The obtained relationships between relative frequencies of the presented and unpresented homophone mates and item accuracy on these tasks were inconsistent with exclusive use of “direct access” but consistent with access of lexical meanings via phonology and application of a “spelling-check” procedure when multiple homophonic meanings are activated.     

GENERALIZED IMITATION AND RESPONSE-CLASS FORMATION IN CHILDREN WITH AUTISM

An experimental analysis of imitation was conducted to examine the influence of response topography on generalization of imitation across three response types. Four children with autism were presented with both reinforced training trials and nonreinforced probe trials of models from vocal, toy-play, and pantomime response types. The probe trials were used to examine generalization within each response type. A multiple baseline design was used to analyze percentage of matching and nonmatching responses to models across response types. This study, the first to analyze imitative response classes in children with autism, showed that imitation generalized from reinforced training models to nonreinforced probe models within a response type, but it did not generalize across response types. Thus, functional response classes determined by topographical boundaries were exhibited within generalized imitation.
