Methodological problems with the use of the retroactive interference design to infer what is stored

The retroactive interference paradigm has been used in a variety of settings to investigate the nature of the representation of memory. Much of the research using this paradigm is methodologically flawed because it involves treatment comparisons which are inappropriate. It is argued that comparisons must be made between presentation conditions having the same interpolated activity and that, in addition, evidence is required that the differences are not confounded by acquisition level differences if one is to infer mode-specific interference and representation. The methodological issues are discussed in detail and the utility of the retroactive interference design is questioned. Studies employing the design are reviewed, and several conclusions are drawn: (1) there has been no unambiguous demonstration of visual mode-specific interference, (2) there has been no clear demonstration that imagery instructions produce memories that are more susceptible to visual than to auditory interpolation, and (3)no clear demonstrations are yet available that memory for spatial location is more susceptible to visual interference than memory for letters.     

Bounding of letter sequences and the integration of visually presented words

Ss wrote down letters that were presented briefly in various temporal and geometric arrangements. Results reveal marked impairment in processing more than one temporally extended word in parallel. The impairment cannot be attributed to spatial separation of letters by itself, to sequence, or to inability to discriminate the letters. The concept of ‘bounding’ is introduced to account for the perception of familiar words in a continuing flow of information; the results suggest that only one object can be bounded at a time. They also suggest that the information that guides the eyes' movements in reading is qualitatively different from the information extracted from the printed text.     

A dimensional approach to the circular ordering of the emotions

A circular ordering of eight primary emotional categories was derived from the postulated underlying dimensions of hedonic and autonomic arousal. The model was contrasted with other approaches in the literature and then compared with a similar model proposed by Plutchik (1980) in postdicting the pattern of results in several studies in the literature. The results of two empirical studies based upon the present model were then presented. It was concluded that sufficient empirical support and advantage, compared with other models, was found to warrant further research.     

The effectiveness of various treatment techniques on different degrees and durations of sleep-onset insomnia

Mild and moderate insomniacs were randomly assigned to one of five group therapy conditions: relaxation without muscle-tension, stimulus control plus relaxation without muscletension, placebo, self-monitoring, and waiting list. Mild insomniacs were differentiated according to the duration of their sleep disturbance. Insomniacs were told that improvement would not be noticeable until after the final therapy session. During this counterdemand period, the two relaxation groups showed significantly greater decreases in sleep onset latency than the control conditions. In addition, it appeared that duration affected treated outcome. The effectiveness of treatment packages and self-monitoring in alleviating insomnia is briefly discussed.     

Using a personal robot to teach young children.

Seventy-five preschool children were instructed about birds by a human teacher, a moving personal robot, a stationary personal robot, and a tape recorder. How much the children learned and how much attention the children paid were compared for each type of instruction. The children learned when they were taught by the human teacher and when they were taught by the animated and the stationary robots. The children paid more attention to the live teacher and to the moving robot than they did to the stationary robot or to the tape recorder. The difference between the amount of attention the children paid to the animated robot and the amount of attention they paid to the human teacher was not statistically significant.     

Individual differences in perceived pinch force and bite force

Six subjects made cross-modalmatches of pinch force and bite force to an electrocutaneous st4niulus. The electrocutaneous stimulus consisted ofbursts ofpulses, and the intensity ofthe stimulus was varied by changing the number of pulses per burst. All of the individual matching functions were fit well by powerfunctions. The scaling constants and exponents ofthe power functions covaried systematically with the maximum pinch force for 5 of the 6 subjects. The relationship was consistent with the hypothesis that subjects perceive their physical maxima equally, in agreement with Borg’s theory of relative perceived exertion. For both pinch force and bite force functions, the scale factors could be described by a single linear function ofthe exponents, suggesting that all of the matching functions converged at a single point with extreme values.     

Kenotic Trinitarian Panentheism

Abstract :  The "openness of God" movement has made a bold, even courageous move away from static models of God. Yet, as the articles here by Pinnock and Bracken show, divisions remain that call for mediation. Both sides have failed to see that a closer connection is possible between process and orthodox thought. The framework is panentheism , the belief that the world is in some sense within God, even though God also transcends the world. Process thinkers are right to conceive God even more radically as the "supremely related one," yet mistaken in their belief that creation ex nihilo and trinitarian models of God are thereby excluded.     

Self-determination and the consequences of social comparison

The present research examined the consequences of social comparison as a function of individual differences in self-determination. Competing hypotheses were made regarding whether the effects of social comparison would be determined more by the tendency toward pressure and ego-defensiveness (higher controlled orientation), by the absence of choice and unconditional positive self-regard (lower autonomy orientation), or both. A forced comparison was created in which 79 college students completed a word finding task and received feedback about their performance along with that of a better or worse performing confederate. Autonomy orientation moderated comparison consequences such that less autonomous individuals experienced increased negative changes in affect and decreased self-esteem when paired with a better performing other. This was especially true, for affect, when participants had been told that the task was related to intelligence. Results provide preliminary support for integration of self-determination and social comparison theories.     

Questions and reflections: the use of motivational interviewing microskills in a peer-led brief alcohol intervention for college students

The purpose of this study was to examine the association between peer facilitator adherence to motivational interviewing (MI) microskills and college student drinking behavior. First year students (N=67) took part in a Brief Alcohol Screening and Intervention for College Students (BASICS) led by peer facilitators trained in MI and BASICS. Participants were assessed pre- and 2 weeks post-intervention on contemplation to change, as well as, pre- and 3 months post- intervention on drinking quantity. Independent coders used the Motivational Interviewing Treatment Integrity scale (MITI, Moyers, Martin, Manuel, & Miller, 2003) to evaluate therapist MI adherence. Peer facilitators met beginning proficiency in MI on scores of empathy, the ratio of MI adherent behaviors to non-adherent behaviors and the ratio of open questions to total questions as defined by the MITI. Results indicated that a higher number of closed questions was related to less contemplation and a higher number of open questions was related to more contemplation post intervention. A higher number of simple reflections was associated with increased drinking at the 3 month assessment, however, complex reflections were found to attenuate the effect of simple reflections on changes in drinking. These findings highlight the importance of competent reflective listening skills and the need for continual training and supervision for peer facilitators.
