“Throwing Baby out with the Bath water#x201D;: Some Reflections on the Evolution of Reproductive Technology}

This article discusses section 156 of the Criminal Justice and Public Order Act 1994 which prohibits the use of eggs from aborted female foetuses for the purposes of reproduction. I argue that the pre-legislative debates focus only on the biological relationship between the aborted foetus and any ensuing child and foreclose the possibility of useful discussion about the potential merits of such technology. Kristeva's theory of abjection has been used in order to elucidate the strength of feeling about the use of eggs from the expelled foetus. I suggest that the ‘yuk’ factor stems from the potential for the blurring of the boundaries between life and death. In addition, I suggest that the stress placed on the biological link means that the foetus is ascribed special properties not given to live donors. Woman's very crucial role in reproductive technologies is therefore erased. The article argues that there are very good reasons why the debate on the subject should remain open. At present women donors have to undergo highly intrusive procedures in order to give eggs and the process is not without its health risks. The use of eggs from aborted foetuses certainly raises important consent issues but these could be addressed by placing women at the centre of the decision making process, starting with the recognition that it is women and not foetuses who have the remit and responsibility for giving consent for the use of their genetic material. Moreover, there should be an acknowledgement that women are perfectly capable of making informed decisions about donation and of considering the potential implications of participating in egg donation.

P-technique factor analyses of the Multiple Affect Adjective Check List (MAACL)

The Multiple Affect Adjective Check List (MAACL) has been found to have five first-order factors representing Anxiety, Depression, Hostility, Positive Affect, and Sensation Seeking and two second-order factors representing Positive Affect and Sensation Seeking (PASS) and Dysphoria. The present study examines whether these first- and second-order conceptions of affect (based on R-technique factor analysis) can also account for patterns of intraindividual variability in affect (based on P-technique factor analysis) in eight elderly women. Although the hypothesized five-factor model of affect was not testable in all of the present P-technique datasets, the results were consistent with this interindividual model of affect. Moreover, evidence of second-order (PASS and Dysphoria) and third-order (generalized distress) factors was found in one data set. Sufficient convergence in findings between the present P-technique research and prior R-technique research suggests that the MAACL is robust in describing both inter- and intraindividual components of affect in elderly women.This paper is based on the doctoral research of the first author and was partially supported by the National Institute of Aging Grant T32 AC 00048-12 to The Pennsylvania State University and a Grant-in-Aid of Research from Sigma Xi, The Scientific Research Society.

Basing the treatment of stereotypic and self-injurious behaviors on hypotheses of their causes.

Stereotypic and self-injurious behaviors are common forms of maladaptive responding demonstrated by severely handicapped persons. Various review papers suggest that no single treatment procedure is universally effective. Although there may be many reasons for this finding, one could be that people engage in these behaviors for various reasons, and that procedures that are incompatible with the cause of the behavior are unlikely to be effective. These studies also suggest many hypotheses for the development and maintenance of these behaviors, three of which are the self-stimulation, positive reinforcement, and negative reinforcement hypotheses. The purpose of this paper was to determine whether one of these hypotheses could be matched to the cause of the behavior and used as an effective treatment procedure. We therefore compared one hypothesis with one other for 3 subjects in a three-phase study. During baseline, data were taken in two classrooms for each subject, and a judgement was made about the hypothesis most likely to be related to the cause of the behavior. During the second phase, a treatment based on that hypothesis was used in one classroom, and a treatment based on another hypothesis was used in the second classroom. During the third phase, the treatment that was most effective in the second phase was used in both classrooms. Results showed that a successful treatment program can be developed on an hypothesis of why the behavior occurred during baseline. Results are discussed in terms of supporting the argument that treatment programs should be based on a functional analysis of the behavior in its environmental context.     

MODIFICATION OF VERBAL BEHAVIOR OF THE MENTALLY IMPAIRED ELDERLY BY THEIR SPOUSES

Speaking disorders frequently result in serious consequences for mentally impaired elderly people. Two examples are presented illustrating the modification of both excess and deficit rates of talking via differential reinforcement procedures. Two men exhibiting verbal disorders severe enough to impair social interactions and lead to possible nursing home placement were treated by teaching their spouses to reinforce positive and ignore undesired verbal responses. Problem behaviors were reduced sufficiently to permit continued home care, and alternative positive behaviors were increased. These findings suggest that verbal behavior of the mentally impaired elderly can be affected by applying systematic consequences and can be modified by relatively simple procedures. These procedures provide an alternative to the negative effects of labels associated with either aversive or deficient verbal behaviors, promote more positive activities, and enable continued residence at home. Further, this research provides support for the generality of the utility of training spouses to serve as behavior therapists for the impaired elderly.     

Positive conditioned suppression: an explanation in terms of multiple and concurrent schedules

Rats performed under a baseline variable-interval schedule of food presentation. A response-independent food schedule was then superimposed on the baseline schedule for different periods of time across different conditions. The response-independent schedule operated for the whole session in some conditions, intermittently for sixty second periods in some, and intermittently for ten-second periods in others. Under these latter two sets of conditions, the response-independent food schedule was stimulus correlated and alternated with the baseline schedule according to a multiple schedule. Response-independent food presentations always suppressed responding. The degree of suppression tended to increase the longer the period of response-independent food. Control conditions, in which the superimposed schedule was response-dependent, rather than response-independent, did not produce response suppression. The results fit an analysis of positive conditioned suppression phenomena in the context of multiple and concurrent schedule effects.     

The effects of violent video games and shyness on individuals’ aggressive behaviors

The general aggression model (GAM) has suggested that the interaction between person factors (e.g., personality variables) and situation factors (e.g., playing violent video games [VVGs]) can increase individuals’ aggressive behaviors through their cognition (e.g., hostile attributions), affect (e.g., negative affect), and/or arousal. The present study employed a modified competitive reaction time task to test the effects of shyness, violent (vs. nonviolent) gameplay, and shyness on individuals’ positive–negative affect, hostile attributions, and aggressive behaviors. In addition, the present study also employed structural equation modeling (SEM) to test the mediation (by cognition and affect) and moderation (by shyness). Results showed that playing a VVG increased aggressive behaviors, negative affect, and hostile attributions primarily among shy participants. In addition, the results of SEM also revealed that this moderating role was mediated by negative affect and hostile attributions. The present study supported GAM and showed that individuals’ aggressive behaviors are differentially susceptible to VVGs, depending on their level of shyness in a “for bad and for worse” manner.     

Roles of cognitive load and self-relevance during emotional information searching on decision-making

Older adults have been found to favor positive stimuli over negative stimuli; further, developing a negative preference may be a cognitively demanding process. In the present study, we focused on the joint effects task self-relevance and cognitive load have on older adults' emotional information preferences when performing decision-making. To examine this, we used multi-attribute decision tasks and process-tracing procedure to measure their searching process. The study composed of a 2 (age: young/old) × 2 (cognitive load: load/non-load) × 3 (attribute valence: positive/neutral/negative) × 3 (task self-relevance: high/medium/low) mixed design. Sixty-one young adults and 62 older adults viewed 5 (alternatives) × 5 (attributes) decision matrices that contained positive, negative, and neutral information, with the total views and mean time spent viewing each different valence (positive, negative, and neutral information) set as dependent variables. The results indicated that both young and old adults have no emotional information preference in regard to self-relevance. When under no cognitive load, both positive and negative information were viewed more than neutral information; however, under cognitive load, preference for negative information decreased; this effect size was more robust in older adults. There was also a main effect of self-relevance on total views and mean checking time, with attributes concerning higher self-relevance tasks being more likely to attract attention. Older adults exhibited a consistent hedonic focus, even in highly self-relevant contexts; however, this effect disappeared under cognitive load. Overall, the findings suggest that cognitive resources play an important role in emotional information processing during decision processes.     

Maintenance of responding by squirrel monkeys under a concurrent shock-postponement, fixed-interval shock-presentation schedule.

A chain-pulling response was initially developed under a shock-postponement (avoidance) schedule with two squirrel monkeys. Few responses occurred on a lever where responding initially had no scheduled consequence or, subsequently, when a 3-minute fixed-interval shock-presentation schedule was concurrently arranged for lever responses. Appropriate rates and patterns of lever responding developed and were later maintained under the fixed-interval 3-minute shock-presentation schedule alone when the chain and shock-postponement schedule were removed. When both the shock-postponement and shock-presentation schedules were again simultaneously in effect, steady rates of chain pulling were maintained by the shock-postponement schedule and positively accelerated rates and patterns were maintained on the lever by the shock-presentation schedule. Response rates under both schedules were directly related to shock intensity. A history of exposure to a shock-postponement schedule, even though with a topographically different response and manipulandum, was sufficient for the development and eventual maintenance of responding by the presentation of shock. Further, differential performances can be maintained simultaneously by the presentation and postponement of electric shock.     

Factors Influencing Condom Use Among African American Women: Implications for Risk Reduction Interventions

Examined factors associated with condom use in a community-based sample of 423 sexually active African American women. Measures were selected to reflect the components in prevailing models of health behavior. Condom users were higher on AIDS health priority, prevention attitudes, stage of change, behavioral intentions, reported more frequent and comfortable sexual communication with partners, perceived greater partner and peer approval for condom use, and reported that peers also used condoms. Women in exclusive relationships evidenced earlier stage of change, lower intentions to use condoms, fewer peers who engaged in preventive behaviors, perceived themselves to have lower risk, and had lower rates of condom use, higher education, and family income. Women in fluid relationships were at particularly high risk, with lower rates of condom use relative to women not in a relationship and greater sexual risk for HIV. Implications for HIV-risk reduction interventions with African American women are discussed.
