Parental Perceptions of Child Development Among Low-Income Mexican American Families

Parents' perceptions of child development are influenced by complex interactions among cultural, social, and economic factors. Insights into how parents from culturally diverse societies perceive the development of their children might explain why different cultural groups foster or value the development of different skills in their children. In this study, we explored the perceptions of child development among low income Mexican American parents. A series of ethnographic interviews were conducted with eight Mexican American families who had preschool children. Qualitative data analyses yielded three main themes that were important to these parents: family attitudes and values, changes, and adaptations. For these parents, the development of social attributes in children, that will enable them to function within their own cultural group, was as important as the development of cognitive or motor skills. Service providers, such as school and mental health personnel, should take into account cultural differences in parents' perceptions of the importance of various developmental milestones for their children when suggesting interventions typically used by parents in the dominant culture.     

Selective Synaptic Plasticity within the Cerebellar Cortex Following Complex Motor Skill Learning

Complex motor skill learning, but not mere motor activity, leads to an increase in synapse number within the cerebellar cortex. The present experiment used quantitative electron microscopy to determine which synapse types were altered in number. Adult female rats were allocated to either an acrobatic condition (AC), a voluntary exercise condition (VX), or an inactive condition (IC). AC animals were trained to traverse an elevated obstacle course requiring substantial motor coordination to complete. VX animals were housed with unlimited access to running wheels and IC animals received no motor training but were handled briefly each day. Results showed the AC animals to have significantly more parallel fiber to Purkinje cell synapses than both the VX and IC animals. No other synapse type was significantly altered. Thus, the learning-dependent increase in synapse number observed within the cerebellar cortex is accomplished primarily through the addition of parallel fiber synapses.     

The effects of nutritional supplements on the symptoms of fibromyalgia and chronic fatigue syndrome

This article reports the results of a within-subject design. Fifty subjects with a physician diagnosis of fibromyalgia (FM) and/or chronic fatigue syndrome (CFS) were interviewed using a structured interview form. Each subject was interviewed initially, and again nine months later (follow-up). Subjects had, on their own, consumed nutritional supplements including freeze-dried aloe vera gel extract; a combination of freeze-dried aloe vera gel extract and additional plant-derived saccharides; freeze-dried fruits and vegetables in combination with the saccharides; and a formulation of dioscorea complex containing the saccharides and a vitamin/mineral complex. With medical treatments, approximately 25 percent of FM patients improved, but the beneficial effects of medical treatment rarely persist more than a few months. All subjects in this study had received some form of medical treatment prior to taking the nutritional supplements, but none with enduring success. Nutritional supplements resulted in a remarkable reduction in initial symptom severity, with continued improvement in the period between initial assessment and the follow-up. Further research is needed to verify these results, specifically crossover designs in well-defined populations.     

Self-limited and unlimited word usage during problem solving in two telecommunication modes

Subjects using oral modes of communication generate far more verbiage than do subjects using handwittenn or typewritten modes to solve the same problems. This study tested two alternative hypotheses to account for this disparity: (1) written modes produce a hard copy of interchanges, thereby compensating for the limitations of short-term memory and reducing the need to repeat information, and (2) talking is so easy that there is no incentive to be concise in oral modes. Two-person teams solved problems either by voice or by teletypewriter. Half the teams were given a monetary incentive to use as few words as possible. No such request was made of the control teams. Subjects in the brevity condition, regardless of the communication mode, greatly reduced verbiage with no increase in time or decrease in accuracy. Moreover, subjects in the brevity-voice condition used even fewer words than did subjects in the control-teletypewriter condition. These results, then, lend weight to the second hypothesis.     

Self-Esteem, Erotophobia, and Retention of Contraceptive and AIDS Information in the Classroom

It has been well documented that people with negative emotional reactions to sex (e.g., "erotophobia,""sex guilt") have less knowledge about contraception than do people with more positive reactions. Recent research has suggested that this deficit is not related to an inability to learn the information, but is due at least in part to the fact that erotophobics actively avoid contraceptive information. The current study was designed to examine the role of erotophobia and high self-esteem in resistance to learning sexual information. More specifically it compared pretest and posttest knowledge of contraception and AIDS in high self-esteem and low self-esteem, erotophobia, and erotophilic women in a university class on human reproduction. As expected, high self-esteem erotophobic subjects were less Likely than other subjects to retain contraceptive and AIDS information presented in the class. Implications of this study for contraceptive and AIDS educational strategies are discussed.     

Changes in human figure drawings during intensive treatment.

This article examines change in the human figure drawings (HFDs) of 32 seriously disturbed young adults during the course of intensive inpatient treatment. HFDs drawn at the time of admission were compared with HFDs obtained more than 1 year after intensive treatment began; both sets were scored on the Goodenough-Harris Scale (GH) and the Robins Balance-Tilt Scale (RBT). The findings indicate that the HFDs significantly improved over the course of treatment, but only for those patients judged introjective, not anaclitic. These findings are consistent with prior research on the same population that were based on analyses of clinical case records and Rorschach protocols (Blatt, Ford, Berman, Cook, & Meyer, 1988). Significant change in the HFDs over the course of treatment suggests that the HFDs provide a unique and independent dimension for assessing therapeutic change.     

The Acquaintance Predicament of a Rape Victim1

The acquaintance predicament of a rape victim was examined in six experiments with between-subjects designs with samples drawn from the undergraduate student population of the University of Bombay. The experiments used rape vignettes for the manipulation of all independent variables except subject's sex and were done in three pairs such that each pair had the same independent variables and first dependent measure, namely, recommended years of imprisonment for the rapist. The second dependent measure was attributed victim's fault in the first experiment and perceived likelihood of rape in the second experiment of each pair. The first pair of experiments had a 2 (subject's sex) × 2 (acquainted vs. unacquainted rapist) × 3 (rapist's status: manager, stenotypist, or watchman) × 2 (complaint vs. no complaint by victim) design, with the rape victim being described as a stenotypist. The second pair of experiments differed from the first pair in only one respect, with victim's marital status (married vs. divorced victim) replacing the independent variable of complaint of the first pair. The third pair of experiments had a 2 (subject's sex) × 2 (physically hurt vs. not hurt victim) × 5 (rapist's relationship with victim: husband, fiance, friend, acquaintance, or stranger) design. Female subjects, as compared to male subjects, recommended longer imprisonment for the rapist, attributed less fault to the victim, and perceived greater likelihood of rape. The victim was attributed less fault in case of stranger rape versus acquaintance rape and also less fault in the complaint versus the no complaint condition. Longer imprisonment was recommended for the rapist when the victim was physically hurt rather than not hurt.     

When do I ponder? The role of elaboration in counterfactual thinking

The counterfactual thought such as “If only I had…” has a powerful impact on people's subsequent behavioral intentions. The literature has documented what may happen with CFT. But little has been done to investigate how CFT produces these effects. In this research, three studies provided evidence to show that elaboration rather than priming is the mechanism for CFT to have an effect on behavioral intentions; and the factors such as argument strength, outcome severity, and goal valence may interfere with such counterfactual effects. These theoretical contributions to the CFT literature offer important managerial implications and help marketers determine optimal persuasion strategies to influence consumers' information processing style.     

Not all missed opportunities cast the same shadow: Voluntary inaction reduces the “sting” of missed sales promotions

How do consumers who miss extremely attractive sales promotions respond to merely attractive opportunities they later encounter when prices return to higher levels? The literature on inaction inertia suggests that the more attractive the missed opportunity, the less likely a consumer is to accept the subsequently encountered inferior opportunity, indicating that consumers may stay undecided. Thus, consumers are believed to be negatively influenced by the shadow of the attractive opportunities they missed. This has adverse consequences for both consumer and firm welfare. Yet, we sometimes do see consumers buying even after missing a sale. We draw from the literature on regret and personal responsibility to hypothesize the conditions that would allow the consumer to remain uninfluenced by the attractiveness of the missed opportunity. In three studies, we find support for the idea that personal responsibility for missing the first opportunity allows consumers to be less influenced by its attractiveness when they see a second inferior opportunity compared to conditions in which they were not personally responsible for missing the first opportunity; this bodes well both for consumer and marketer welfare.
