Problem-solving skills training: Social validation and generalization

This study developed and evaluated a program for teaching a verbal problem-solving strategy to mildly mentally handicapped adults. Six general areas were targeted for training: Community Awareness, Authority Figures, Peer Issues, Stating One's Rights, Emergencies and Injuries, and Safety. The program features response-specific feedback, modeling, self-monitoring, positive reinforcement, response practice, self-correction, and individualized performance criterion levels. The experimental group (N = 3) received baseline, training, probes, and pre/posttraining generalization assessments, whereas the control group (N = 3) received only the pre/posttraining assessments. The generalization and probe assessments contained situations that were both similar and dissimilar to the training situations. The three month posttraining results revealed that the experimental subjects' problem-solving skills had generalized to both types of situations, whereas the control group showed little overall change. Furthermore, the experimental group's three month scores were comparable to those of a group of nonhandicapped individuals. Issues related to these results and suggestions for future research are discussed.     

Individual differences in children's event memory reports and the narrative elaboration technique

Children between 7 and 8 years old took part in a staged event at school and 1 week later were assessed using a short form of the Wechsler Intelligence scale for children (third edition) and measures of metamemory, narrative ability, and socioeconomic status. Two weeks following the event, children either received narrative elaboration training (NET; K.J. Saywitz & L. Snyder, 1996) and were prompted with the four NET cue cards at interview; received verbal prompts corresponding to the cue card categories, but without prior training; or were presented with the cards at interview without prior training. Children given verbal labels as prompts recalled as much information as children who received NET training and cue cards. Measures of intelligence were predictive of amount recalled for cards-only children but not for the other 2 groups, indicating that differences in recall between low- and high-IQ groups were attenuated when recall was supported by NET training or verbal prompting.     

Problem-solving skills training for psychiatric inpatients: An analysis of generalization

A program for teaching problem-solving skills was evaluated with six psychiatric inpatients in a multiple baseline across groups design. Subjects received training on 12 problem situations and the generalization of verbal problem-solving to six novel situations was assessed via probes presented by a novel person in an untrained setting. The generalization of overt behavior was assessed via pre/post contrived in vivo assessments that contained six situations used in training. The in vivo situations were integrated within a sequence of ongoing events in an effort to enhance the ‘naturalness’ of the assessment. The probes revealed some improvement in verbal problem-solving skills, whereas minimal improvement occurred in the post in vivo test. Following the study, an attempt was made to enhance performance by having the trainer conduct a probe and adding verbal prompts to evoke problem-solving during an additional in vivo assessment. Both efforts produced improvements in subjects' performance to a level near that achieved by a normative sample of 20 individuals. The results suggest that in vivo problem-solving may be dependent on the methods used in presenting problem situations as well as situational factors. Issues related to these results and suggestions for future research are discussed.     

Teaching a Problem Solving Strategy to Inpatient Adolescents:

This study evaluated a recently developed program for teaching problem solving skills. Six inpatient adolescents received training in four general areas: Authority Figures; Peer Issues; Community Resources; and Alcohol and Drugs. The program featured response-specific feedback, modeling, self-monitoring, visual cues, positive reinforcement, response practice, self-correction, and individualized performance criterion levels. A multiple baseline across groups design was used in which each group (N + 3) received baseline, training, probes, and pre/post training generalization assessments. Generalization was assessed to two different sets of untrained problem situations that contained similar and dissimilar situations to those used in training. One set was assessed during probes and the other in pre/post evaluations. Both the probes and post assessment results revealed that the subjects' verbal problem solving skills had generalized to both types of situations. Furthermore, the subjects' three-month post assessment scores demonstrated partial maintenance and were comparable to those of a group of normal high school students. Issues related to these results and suggestions for future research are discussed.     

Are choices based on conditional or conjunctive probabilities in a sequential risk-taking task?

In this study, we examined participants' choice behavior in a sequential risk-taking task. We were especially interested in the extent to which participants focus on the immediate next choice or consider the entire choice sequence. To do so, we inspected whether decisions were either based on conditional probabilities (e.g., being successful on the immediate next trial) or on conjunctive probabilities (of being successful several times in a row). The results of five experiments with a simplified nine-card Columbia Card Task and a CPT-model analysis show that participants' choice behavior can be described best by a mixture of the two probability types. Specifically, for their first choice, the participants relied on conditional probabilities, whereas subsequent choices were based on conjunctive probabilities. This strategy occurred across different start conditions in which more or less cards were already presented face up. Consequently, the proportion of risky choices was substantially higher when participants started from a state with some cards facing up, compared with when they arrived at that state starting from the very beginning. The results, alternative accounts, and implications are discussed.     

Interviewing preschoolers from low- and middle-SES communities: a test of the narrative elaboration recall improvement technique.

Tested the effectiveness of Narrative Elaboration (NE), a memory enhancement and interview preparation technique, with 99 preschool children from middle- and low-socioeconomic status (SES) communities. Half were trained with the NE intervention to utilize generic visual cue cards to provide forensically relevant details within four information categories: participants, settings, actions, conversation. One day after the NE training, interviewers asked participants to recount an event staged 1 week earlier. Analyses revealed that NE-trained children from both SES levels recalled significantly more about the event than control children, without producing more errors, particularly when given an opportunity to elaborate on initial free recall using the visual cue cards. No such difference in free recall alone was found. Additionally, preschoolers from low-SES communities generated more errors than their middle-SES counterparts, regardless of treatment condition.     

The Effects of Presenting Multidigit Mathematics Problems in a Realistic Context on Sixth Graders' Problem Solving

Mathematics education and assessments increasingly involve arithmetic problems presented in context: a realistic situation that requires mathematical modeling. This study assessed the effects of such typical school mathematics contexts on two aspects of problem solving: performance and strategy use. Multidigit arithmetic problems presented in two conditions—with and without a realistic context—were solved by 685 sixth graders from The Netherlands. Regarding performance, the same (latent) ability dimension was involved in solving both types of problems, and the presence of a context increased the difficulty level of the division problems but not of other operations. Regarding strategy use, strategy choice and strategy accuracy were not affected by the presence of a problem context. In sum, the presence of a typical context in multidigit arithmetic problems had no marked effects on students' problem-solving behavior, which held for different subgroups of students with respect to language ability and gender.     

Effects of informative peripheral cues on eye movements: Revisiting William James’ “derived attention”

Two experiments examined effects of peripheral information on the latency of saccadic eye movements. In Experiment 1, simple target stimuli were presented to the left or right visual field. Prior to each target, a pair of cue letters was presented for 40msec bilaterally. The relative location of the letters (W-S or S-W) was related to target location, but participants were not informed of this contingency. After a brief practice period, saccadic latencies were faster for targets at the likely location, as indicated by the letter pair. This derived peripheral cueing effect was related to participants' awareness of the relation between cue type and target location. Experiments 2A and 2B employed monocular viewing in order to compare performance across the nasal and temporal visual fields. The effect observed in Experiment 1 was confined to the nasal visual field. In a reflexive orienting condition, the effect of a unilateral letter cue was larger in the temporal visual field. It is concluded that the neurocognitive processes responsible for derived peripheral cueing are distinct from those involved in either reflexive or voluntary orienting.     

The acquisition,maintenance, and generalization of first-aid skills by youths with handicaps

This study validated a program for teaching first-aid skills to four youths with handicaps. Two first-aid skills were targeted for training: treating minor wounds that continue to bleed (not severe) and treating minor burns. Also, data were gathered on the treatment of abrasions to assess the collateral effects of the program. The program featured an activity book with task-analysed illustrations, puppets, a first-aid kit, reinforcement, and corrective feedback. A multiple base-line design across first-aid skills was replicated across each of the four participants. Probes and pre-/post-training assessments were conducted to measure generalization via the treatment of the injuries of others, as well as self-injuries; additionally, assessments were conducted in the participants' natural homes to determine generalized effects across settings. Results revealed that the participants had generalized and maintained (up to 66 weeks) the acquired first-aid skills. The program appears to offer promise as a means of teaching first-aid skills to youths with handicaps, since it produces effects which generalize across settings and novel situations, and which maintain over time.     

Assessment of role-play generalization across qualitatively different situations

Role-play generalization of newly acquired assertive behavior was assessed across different response situations in a clinical outpatient sample. Prior to assertive training, subjects completed two paper-and-pencil inventories and a series of role-play situations. Behavioral role-play scenes included four response forms: making requests, expressing affection, standing up for rights, and expressing displeasure. Subjects were randomly assigned to treatment or test-retest conditions and the treatment subjects received six 2-hr sessions of assertion training using modeling, behavior rehearsal, instruction, positive reinforcement, assignedin vivo homework, bibliotherapy, and daily recordings of assertive behavior. Posttreatment, subjects completed the paper-and-pencil measures, trained role-play scenes, and a set of dissimilar untrained scenes requiring different response forms (giving compliments, receiving compliments; refusing unreasonable requests and expressing justified anger). Videotapes were rated blindly and in random order at the conclusion of the study by trained judges. Treatment and test-retest subjects were equivalent prior to training. Posttreatment for the two groups differed in self-report, role-play behavior in trained situations, and role-play behavior in untrained dissimilar situations (allp<.001). MANOVA with repeated measures confirmed that trained and generalization role-play scenes were quantitatively, as well as qualitatively, different, confirmed that treatment and test-retest subjects exhibited different performance levels posttreatment on both trained and generalization scenes, and revealed four significant interactions (allp<.001). Implications of the interactions are discussed. Canonical correlation revealed that subjects displayed significant commonality in their behavioral profiles across different response forms. The findings indicate that complex training resulted in generalization from trained situations to untrained and dissimilar generalization scenes for the clinical outpatient sample.     

EFFECTS OF COMMUNITY-BASED,VIDEOTAPE, AND FLASH CARD INSTRUCTION OF COMMUNITY-REFERENCED SIGHT WORDS ON STUDENTS WITH MENTAL RETARDATION

Community-referenced sight words and phrases were taught to adolescents with mild and moderate mental retardation using three instructional methods in two locations. Words were presented on flash cards in a school setting, on videotape recordings in a school setting, and on naturally occurring signs in the community. During each session, participants were taught one third of the words in each of these conditions and were then tested at the community sites. A constant prompt delay procedure was used to promote stimulus control to the experimenter's cue initially and then to transfer control to the textual stimuli used for training. A multiple baseline across participants design was employed. Results showed rapid acquisition of the community-referenced sight words in all three training conditions and generalization from the flash card and videotape conditions to the community sites.     

Empirical tests of the recognition heuristic

The recognition heuristic postulates that individuals should choose a recognized object more often than an unrecognized one whenever recognition is related to the criterion. This behavior has been described as a one‐cue, noncompensatory decision‐making strategy. This claim and other assumptions were tested in four experiments using paired‐comparison tasks with cities and other geographical objects. The main results were (1) that the recognized object was chosen more often than the unrecognized one when the recognition cue was valid; (2) that participants' behavior did not reflect the recognition validity of their own knowledge; (3) that a less‐is‐more effect (i.e., better performance with less knowledge) was either absent or of only small size; and (4) that judgments were influenced by further knowledge, which could even compensate for the recognition cue. In sum, the recognition cue represents an important piece of knowledge in paired comparisons, but apparently not the only one. Copyright © 2006 John Wiley & Sons, Ltd.     

Competitiveness and the Similarity of Preferred Coworkers1

The study investigated effects of different work contexts on the individual's desire to work with a similar or dissimilar coworker. Business students (N= 536) were assigned to 1 of 3 conditions (competitive task, skill‐development task, and nonspecific task) and were asked to describe their preferred coworker for that task. Individuals were expected to prefer coworkers whom they perceived as similar in noncompetitive situations, but those whom they perceived as dissimilar in competitive situations. Further, it was hypothesized that the type of similarity emphasized (skills, personal values, and personal style) would reflect the type of anticipated interaction. As expected, participants in competitive conditions chose coworkers with lower skills and generally dissimilar values and personal style. Coworkers selected for the skill‐development condition possessed similar skills and were more similar in values.     

Assessing Personality in the Employment Interview: The Impact of Training on Rater Accuracy

We developed a training protocol to enhance interviewers' knowledge of personality-related cues and, in so doing, improve the accuracy of their personality judgments. Participants (N = 164) watched 3 videotaped mock employment interviews and judged the personality of those interviewees. The trained group was more accurate than the control group for some, but not all, of the rated traits. It was predicted that training would increase participants' dispositional intelligence (knowledge of personality) scores. This hypothesis was not supported, suggesting that trait cue knowledge and dispositional intelligence may function independently in the improvement of rating accuracy. These findings contribute to further articulation of the process underlying accurate personality inferences.     

GENERALIZED EFFECTS OF A PEER-DELIVERED FIRST AID PROGRAM FOR STUDENTS WITH MODERATE INTELLECTUAL DISABILITIES

Peers with mild intellectual disabilities taught first aid skills to 4 students with moderate intellectual disabilities. A multiple probe design across participants was used to examine the effects of the peer teaching program during an acquisition and a partial sequential withdrawal phase. Generalization assessments were conducted in the participants' homes using novel, randomized simulated injuries. Results suggested that the peer teaching program resulted in acquisition of first aid skills, and the participants' skills generalized to the home, to novel simulated-injury locations, and to new trainers. Additionally, a more detailed analysis of the generalized responding suggested that when given a choice among first aid materials, participants treated burns using large adhesive bandages rather than the materials used in training. Participants also successfully treated injuries when novel instructional cues were used. The findings are discussed with respect to training issues, generalization and maintenance of the acquired skills, and the use of peer tutors with disabilities.

Personal problem-solving scoring of the TAT: sensitivity to training

The Thematic Apperception Test (TAT; Murray, 1943) is one of the most frequently taught and administered projective instruments in the United States. Nevertheless, formal scoring systems are not often used when evaluating story responses; thus, the reliability and validity of response interpretations remain controversial. The sensitivity-to-training of a procedure that uses the TAT to assess personal problem-solving skills, namely the Personal Problem-Solving System (PPSS; Ronan, 1990), was evaluated. In Experiment 1, undergraduate students received either detailed (n = 30) or minimal (n = 29) training in the problem-solving skill of generating alternative solutions to personal problems and subsequently wrote responses to three TAT cards. In Experiment 2, subjects received either detailed (n = 22) or minimal (n = 22) training in a utility model of decision making and thereafter responded to the same three TAT cards. Subjects who received detailed training, when compared to their minimally trained counterparts, reported an increase in their knowledge of the relevant problem-solving skill, and this increased knowledge influenced their responses to the TAT cards as measured by the PPSS scores. Implications for the construct validity of the PPSS are discussed.

The Role of Surface Similarity in Analogical Retrieval: Bridging the Gap Between the Naturalistic and the Experimental Traditions

Blanchette and Dunbar (2000) have claimed that when participants are allowed to draw on their own source analogs in the service of analogical argumentation, retrieval is less constrained by surface similarity than traditional experiments suggest. In two studies, we adapted this production paradigm to control for the potentially distorting effects of analogy fabrication and uneven availability of close and distant sources in memory. Experiment 1 assessed whether participants were reminded of central episodes from popular movies while generating analogies for superficially similar versus superficially dissimilar target situations. In Experiment 2, we modified this procedure to assess the retrieval of autobiographic memories, more familiar to participants than fictional episodes. Both studies revealed a strong effect of surface similarity on the retrieval of participants' own sources, thus suggesting that the superficial bias typically observed in experimental studies—and simulated by most computational models—does not originate in a lack of ecological validity.     

Information about the logical structure of a category affects generalization

This paper considers whether information about the logical structure of a category affects how people generalize. We carried out three experiments with the following structure: participants were first presented with a set of training items, and were subsequently asked to decide whether new items belonged to the same category as the training items. Each experiment had two conditions that differed only in terms of the category label provided for the training items; different category labels conveyed different information about the logical structure of the category to which the training items were supposed to belong. In all cases, participants' generalization was greatly affected by such information. Our results suggest that people make the default assumption that category labels correspond to groupings of highly similar objects.
