Children''s Memory and Source Monitoring of Real-Life and Televised Events

It is theoretically and practically important to know whether children confuse memories of different events to which they have been exposed. In two studies, children aged 4 and 10 years watched two related events; one event was live and the other was a video recording. Half of the children watched a video that was similar to the live event, and the remaining children watched a video that was dissimilar. One week later, children in the similar condition confused the two events more than those in the different condition when freely recalling (Experiments 1 and 2) and in response to focused questions (Experiment 1). The 10-year olds reported more information than the 4-year olds and were more accurate overall, confusing the events less than the 4-year olds. When the events were presented 1 day after each other (Experiment 2), the reports were more inaccurate than when the events were separated by a 2-day interval, but this did not affect the number of times the events were confused. The results suggest that mere exposure to similar events in different media can contaminate memories, and the findings are discussed in relation to children's source monitoring and eyewitness memory.     

Sign tracking in cuttlefish (Sepia officinalis)

Two groups of cuttlefish (Sepia officinalis) were used to demonstrate classical conditioning in this species and to determine whether the resulting approach response would be that of sign tracking or goal tracking. For cuttlefish in the paired condition, a flashing light was presented at one end of a long tank followed by food dropped into the center of the tank. For cuttlefish in the unpaired condition, food was dropped into the center of the tank either before or after the flashing-light stimulus. Paired cuttlefish oriented to the light, positioned themselves within striking distance, and occasionally attacked the light. Unpaired cuttlefish showed no reliable response to either stimulus. The results demonstrate that cuttlefish are capable of signal learning and that, under the conditions tested, cuttlefish sign tracked. This study begins a comparative analysis of learning in cuttlefish and offers a possible ecological advantage for sign-tracking behavior.     

MULTICOMPONENT ASSESSMENT AND TREATMENT OF CIGARETTE PICA

We conducted a multicomponent assessment and treatment for 4 individuals who engaged in cigarette pica. During Phase 1, three stimulus preference assessments were conducted to identify (a) the reinforcing component of the cigarette, (b) potential alternative reinforcers that may be used during treatment, and (c) whether the alternative reinforcer would compete effectively with cigarettes. Results were successful in identifying the reinforcing component of the cigarette and suggested the feasibility of using alternative reinforcers during treatment to eliminate cigarette pica. During Phase 2, the effects of two treatment procedures were evaluated. Noncontingent reinforcement (NCR) with the alternative edible reinforcer reduced the pica of 2 of the participants, but effects were not maintained when the initial dense schedule of NCR was thinned. Subsequently, differential reinforcement of alternative behavior with the alternative edible reinforcer was effective in reducing pica for 3 participants. An evaluation of nine treatment procedures failed to identify an effective intervention for the remaining participant; consequently, preventive measures were designed to minimize occurrences of cigarette pica.     

TRAINING AND GENERALIZATION OF SEXUAL ABUSE PREVENTION SKILLS FOR WOMEN WITH MENTAL RETARDATION

Previous research has shown that behavioral skills training to teach sexual abuse prevention skills to women with mental retardation results in skill acquisition but poor generalization. In this investigation we evaluated procedures for enhancing generalization following training. Five women with mental retardation received 10 behavioral skills training sessions followed by in situ training when the skills did not fully generalize. Behavioral skills training resulted in skill acquisition and in situ training produced generalized responding during naturalistic assessments.     

Blocking in the Morris swimming pool.

Four experiments demonstrate that spatial blocking is governed by the same principles that govern blocking in Pavlovian conditioning. In the 2nd stage of each experiment, rats escaped from a Morris swimming pool by swimming to a submerged platform with a beacon attached to it. Test trials were then conducted in the absence of the platform and the beacon to assess the extent to which subjects had learned about the position of the platform with reference to the room cues. For the 1st stage of their training, rats either swam to the platform and beacon in the presence of curtains that prevented the room cues from being seen (Experiments 1 & 2), or they swam to the platform and beacon that were moved from trial to trial (Experiments 3 & 4). In each experiment, learning about the room cues in the 2nd stage of the experiment was blocked by the presence of the beacon. This blocking effect was disrupted by changing the appearance of the beacon for the 2nd stage of training or by restricting the amount of exposure to the beacon during the 1st phase of training.     

Resume Characteristics as Predictors of an Invitation to Interview

The resume is the first contact between an organization and a job seeker, but little empirical evidence exits to guide resume development. This study examined the impact of resume characteristics on decisions to interview graduates. It was found that resume characteristics provided an advantage in obtaining an invitation to interview.     

Near Death Experiences and Gnostic Christianity: Parallels in Antiquity

Long considered to be heretical, ancient Gnostic Christian texts unearthed this century display compelling similarities between Gnostic conceptions of life and death and modern NDEs. The Gnostic texts devoted extensive tracts to what readers could expect to encounter when they died. Other passages make numerous allusions to NDE-like experiences that can be realized in this life, most notably the human encounter with a Divine Light. The Gnostic Christian literature gives us one more example of NDEs and similar experiences in the ancient world.     

Visual acuity improvement following fading and feedback training—I. Comparison of myopic and emmetropic volunteers

18 myopes and 18 emmetropes were randomly assigned in pairs to either Fading and Feedback training or a no-treatment control condition. The emmetropes were fitted with plus lenses equivalent to the spherical correction of the paired myope to simulate myopic visual acuity. Extensive visual acuity measures were obtained pre- and post-training. Data analyses indicated significant increases in recognition visual acuity for trained subjects, compared to no-treatment controls. The myopia/emmetropia variable did not interact with training even though there were noticably greater increases in visual acuity for trained myopes compared to the other conditions. Resolution visual acuity did not change as a function of training. These data are discussed in terms of their implications for better understanding the mechanisms responsible for visual acuity increases following behavioural training.     

Evaluation of a sexual abuse prevention program for adults with mental retardation.

Programs to teach sexual abuse prevention skills to persons with mental retardation have rarely been evaluated empirically, and typical evaluations are limited to assessment of the participants' knowledge rather than their performance of specific skills. In the present study, 6 adult women with mental retardation were trained in sexual abuse prevention, and performance was assessed using four separate measures: pretests and posttests of knowledge, verbal report, role play, and naturalistic probes. All women learned the skills but failed to exhibit them to criterion during the probes. We discuss the implications for further training and assessment of sexual abuse prevention skills.
