Stimulus equivalence and arbitrarily applicable relational responding.

Subjects' responses to nonarbitrary stimulus relations of sameness, oppositeness, or difference were brought under contextual control. In the presence of the SAME context, selecting the same comparison as the sample was reinforced. In the presence of the OPPOSITE context, selecting a comparison as far from the sample as possible on the physical dimension defined by the set of comparisons was reinforced. Given the DIFFERENT context, selecting any comparison other than the sample was reinforced. Subjects were then exposed to arbitrary matching-to-sample training in the presence of these same contextual cues. Some subjects received training using the SAME and OPPOSITE contexts, others received SAME and DIFFERENT, and others received SAME, OPPOSITE, and DIFFERENT. The stimulus networks established allowed testing for a wide variety of derived relations. In two experiments it was shown that derived performances were consistent with relational responding brought to bear by the contextual cues. In contexts relevant to the relation of sameness, stimulus equivalence emerged. Other kinds of relational networks emerged in the other contexts. Arbitrarily applicable relational responding may give rise to a very wide variety of derived stimulus relations. The kinds of performances seen in stimulus equivalence do not appear to be unique.     

Derived relational responding: a comparison of match-to-sample and the relational completion procedure

Previous research suggests that the Relational Completion Procedure may be an effective alternative procedure for studying derived relational responding. However, the parameters that make it effective, relative to traditional match-to-sample, remain to be determined. The present experiment compared the Relational Completion Procedure and match-to-sample protocols for training and testing Same and Opposite derived stimulus relations. Trials to criterion and overall pass rate (i.e., yield) in both procedures were compared across three variables: presence versus absence of a confirmatory response requirement, three versus five comparison stimuli, and top-to-bottom versus left-to-right presentation format. Findings demonstrated a facilitative effect of the confirmatory response requirement in both procedures. Training trials to criterion were nominally but not significantly lower during the nonarbitrary training phase in the Relational Completion Procedure compared to match-to-sample, and the overall yield on the arbitrary relational test was greater in the former procedure compared to the latter. The present findings support the further development of the Relational Completion Procedure as an efficient alternative procedure for establishing Same and Opposite relations with adult humans, and with potential applicability to other types of derived relations.     

A transformation of self-discrimination response functions in accordance with the arbitrarily applicable relations of sameness, more than, and less than

In Experiment 1, 2 experimental subjects were given pretraining of nonarbitrary relations that brought their responses under the control of four contextual stimuli; same, opposite, more than, and less than. One control subject was not exposed to this pretraining. The 2 pretrained subjects and the 3rd nonpretrained subject then received training in six arbitrary relations, the following four relations being the most critical: same/A1-B1, same/A1-C1, less than/A1-B2, more than/A1-C2. All 3 subjects were then tested for seven derived relations, the following three relations being the most important: same/B1-C1, more than/B1-C2, less than/B1-B2. The 2 pretrained subjects, but not the nonpretrained subject, showed the derived relations. One of the stimuli (B1) from the relational network and two novel stimuli (X1 and X2) were then used to train three different self-discrimination responses on three complex schedules of reinforcement. That is, all 3 subjects were trained to pick X1 if they had not emitted a response, to pick B1 if they had emitted one response only, and to pick X2 if they had emitted two responses only. The 2 pretrained subjects, but not the nonpretrained subject, showed the predicted transformation of self-discrimination response functions in accordance with the relations of sameness, more than, and less than (i.e., no response, pick B2; one response only, pick C1; and two responses only, pick C2). In Experiment 2, 2 new subjects were employed, and the arbitrary relational training and testing phases were modified to control for a procedural artifact that may have contributed to the results of the first experiment. Experiment 2 replicated the findings of Experiment 1. The pattern of results support the utility of a relational frames approach to understanding derived stimulus relations.     

The effects of relational structure on analogical learning

Relational structure is important for various cognitive tasks, such as analogical transfer, but its role in learning of new relational concepts is poorly understood. This article reports two experiments testing people’s ability to learn new relational categories as a function of their relational structure. In Experiment 1, each stimulus consisted of 4 objects varying on 2 dimensions. Each category was defined by two binary relations between pairs of objects. The manner in which the relations were linked (i.e., by operating on shared objects) varied between subjects, producing 3 logically different conditions. In Experiment 2, each stimulus consisted of 4 objects varying on 3 dimensions. Categories were defined by three binary relations, leading to six logically different conditions. Various learning models were compared to the behavioral data, based on the theory of schema refinement. The results highlight several shortcomings of schema refinement as a model of relational learning: (1) it can make unreasonable demands on working memory, (2) it does not allow schemas to grow in complexity, and (3) it incorrectly predicts learning is insensitive to relational structure. We propose schema elaboration as an additional mechanism that provides a more complete account, and we relate this mechanism to previous proposals regarding interactions between analogy and representation construction. The current findings may advance understanding of the cognitive mechanisms involved in learning and representing relational concepts.     

The impact of open and closed mindsets on evaluative priming

In the present research, we argue that open versus closed mindsets, accompanying ongoing versus completed mental jobs on the prime, determine the size of congruity effects in the evaluative priming paradigm. More specifically, we hypothesised that disfluent primes that resist an easily completed encoding process should induce an open mindset and thereby result in stronger congruity effects than fluent primes that induce closed mindsets. Across two experiments, we applied two different manipulations of prime fluency: gradual demasking (Experiment 1) and colour contrast (Experiment 2). As expected, in both experiments we found robust congruity effects, but only on trials with disfluent (vs. fluent) primes. Results of a follow-up experiment suggest that these effects are not due to attentional processes. We conclude that the mindsets resulting from individuals' activities during encoding are crucial in determining the outcome of evaluative priming effects.     

The impact of supervisory mentoring on personal learning and career outcomes: The dual moderating effect of self-efficacy

Using survey data from 226 employees and their supervisors in four manufacturing companies in China, we found that employee self-efficacy has a dual moderating effect on the impact of supervisory mentoring on subordinate career outcomes. Path analytic tests of mediated moderation suggested that self-efficacy moderates the mediated effects of supervisory mentoring on job performance and career satisfaction through personal learning such that the mediated effect on job performance is stronger when employees have higher self-efficacy, but the mediated effect on career satisfaction is stronger when they have lower self-efficacy.     

The impact of error frequency on errorless and errorful learning of object locations using a novel paradigm

ABSTRACT

Errorless learning (EL) is an approach in which errors are eliminated or reduced as much as possible while learning of new information or skills. In contrast, during trial-and-error???or errorful???learning (TEL) errors are not reduced and are often even promoted. There is a complex and conflicting pattern of evidence whether EL or TEL may result in better memory performance. One major confound in the extant literature is that most EL studies have not controlled for the number of errors made during TEL, resulting in a large variability in the amount of errors committed. This variability likely explains why studies on the cognitive underpinnings of EL and TEL have produced mixed findings. In this study, a novel object-location learning task was employed to examine EL and TEL in 30 healthy young adults. The number of errors was systematically manipulated, allowing us to investigate the impact of frequency of errors on learning outcome. The results showed that recall from memory was significantly better during EL. However, the number of errors made during TEL did not influence the performance in young adults. Altogether, our novel paradigm is promising for measuring EL and TEL, allowing for more accurate analyses to understand the impact of error frequency on a person’s learning ability and style.     

The impact of music on learning and consolidation of novel words

Music can be a powerful mnemonic device, as shown by a body of literature demonstrating that listening to text sung to a familiar melody results in better memory for the words compared to conditions where they are spoken. Furthermore, patients with a range of memory impairments appear to be able to form new declarative memories when they are encoded in the form of lyrics in a song, while unable to remember similar materials after hearing them in the spoken modality. Whether music facilitates the acquisition of completely new information, such as new vocabulary, remains unknown. Here we report three experiments in which adult participants learned novel words in the spoken or sung modality. While we found no benefit of musical presentation on free recall or recognition memory of novel words, novel words learned in the sung modality were more strongly integrated in the mental lexicon compared to words learned in the spoken modality. This advantage for the sung words was only present when the training melody was familiar. The impact of musical presentation on learning therefore appears to extend beyond episodic memory and can be reflected in the emergence and properties of new lexical representations.     

The impact of Parkinson's disease on sequence learning: perceptual pattern learning and executive function

The current study examined the contribution of brain areas affected by Parkinson's disease (PD) to sequence learning, with a specific focus on response-related processes, spatial attentional control, and executive functioning. Patients with mild PD, patients with moderate PD, and healthy age-matched participants performed three tasks-a sequence learning task with a spatial pattern that was incidental to response selection, a spatial cuing task, and neuropsychological tests of executive function. Whereas moderate PD patients failed to show significant sequence learning, mild PD patients performed comparably with controls. Neither group of PD patients was impaired in the control of spatial attention. Sequence learning was correlated with neuropsychological measures of executive function but not with the ability to control spatial attention. These results suggest that the contribution of the brain areas affected by PD to sequence learning extends beyond motor learning to include the learning of perceptual patterns and involves executive function, including cognitive flexibility and set shifting.     

Direct evaluative conditioning in brand placement: The impact of scene valence and prominence on brand placement repetition effects

Whereas previous studies investigated the affect transfer from one specific affective stimulus of the brand placement context (such as an artist or the genre) to the brand, this research study investigates the effect of the valence of various scenes in which the brand is repeatedly placed on brand attitude. Direct evaluative conditioning theory suggests that pairing a brand repeatedly with various positive (negative) stimuli positively (negatively) affects brand attitude. The results of 2 experimental studies indicate that when a brand is repeatedly and prominently placed in different affective scenes of the same valence (a series of either positive or negative scenes), the affect aroused by those scenes influences explicit and implicit brand attitudes. In addition, whereas previous research found negative effects of brand prominence on brand evaluations, this study found that prominence positively moderates the affect transfer from the valence of various scenes on brand attitude. This implies that by placing the brand in various positive scenes, prominent brand placements can have a positive effect on recall and recognition and on brand attitude, which transcends the previously declared paradox of prominent placement.     

The impact of role modeling on protégés' personal learning and work-to-family enrichment

The present study investigates the impact of role modeling as perceived by protégés on their personal learning (i.e., relational job learning and personal skill development) and work-to-family enrichment (WFE). Results from a two-wave field survey of 173 protégés in the People's Republic of China indicate that role modeling positively affects relational job learning and personal skill development. However, personal skill development rather than relational job learning was found to be positively related to WFE and to mediate the relationship between role modeling and WFE. The theoretical and managerial implications of these findings are discussed.

The impact of career exploration and interview readiness on interview performance and outcomes

In a longitudinal study of 78 graduate business students, three aspects of career exploration—environment exploration, self-exploration, and the amount of information acquired—were examined as predictors of interview performance (interview rating and self-rating) and outcomes (call-back interviews and job offers). Environment exploration and the amount of information acquired related significantly with the recruiter's rating of interview performance and interview outcomes; self-exploration correlated with the recruiter's rating of interview performance. Interview readiness variables (perceived past performance, verbal persuasion, and feelings of self-efficacy) correlated modestly with career exploration variables, interview performance ratings, and interview outcomes.     

The effects of situational goal orientation and cultural learning values on team performance and adaptation to change

In this paper, we examine the unique effects of situational goal orientation and cultural learning values on team adaptation to change and the moderating role of cultural learning values in the relationship between goal orientation and team performance and adaptation. To do this, we conducted an experiment using a 2 × 2 × 2 repeated-measures factorial design, consisting of high and low levels of learning values, situational goal orientation (i.e., learning goals and performance goals). The experimental task involved two phases: we looked at team performance in Phase 1 and team adaptation to change in Phase 2. Forty 3-person teams were randomly assigned to four experimental conditions and all teams engaged in a complex bridge-planning task. Performance was measured in terms of the quality of the planned bridge. Results showed independent effects of situational goal orientation and cultural learning values on team performance and adaptation to change. Cultural learning values also moderated the relationship between goal orientation and performance and adaptation to change. Finally, the combination of learning goals and high learning values resulted in the highest levels of initial team performance (Phase 1) and adaptation to change and improved performance (Phase 2), as compared to all other examined conditions.

Motor learning without physical practice: The effects of combined action observation and motor imagery practice on cup-stacking speed

In this study we explored training effects for combined action observation and motor imagery (AO + MI) instructions on a complex cup-stacking task, without physical practice. Using a Graeco-Latin Square design, we randomly assigned twenty-six participants into four groups. This counterbalanced the within-participant factor of practice condition (AO + MI, AO, MI, Control) across four cup-stacking tasks, which varied in their complexity. On each of the three consecutive practice days participants experienced twenty trials under each of the three mental practice conditions. On each trial, a first-person perspective video depicted bilateral cup-stacking performed by an experienced model. During AO, participants passively observed this action, responding only to occasional colour cues. For AO + MI, participants imagined performing the observed action and synchronised their concurrent MI with the display. For MI, a sequence of pictures cued imagery of each stage of the task. Analyses revealed a significant main effect of practice condition both at the ’surprise’ post-test (Day 3) and at the one-week retention test. At both time points movement execution times were significantly shorter for AO + MI compared with AO, MI and the Control. Execution times were also shorter overall at the retention compared with the post-test. These results demonstrate that a complex novel motor task can be acquired without physical training. Practitioners can therefore use AO + MI practice to supplement physical practice and optimise skill learning.
