From Glossy to Greasy: The Impact of Learned Associations on Perceptions of Food Healthfulness

We demonstrate that consumers have learned that unhealthy snacks such as potato chips tend to be sold in glossy packages, whereas healthier snacks such as crackers tend to be sold in matte packages (in studies 1–3). As a result, consumers who see a snack food package with a glossy [matte] surface will infer lesser [greater] healthfulness of its contents (study 4), consume less [more] of it (study 5), and be more likely to choose a glossy [matte] package from an assortment of snack packages if motivated to engage in tasty [healthful] eating (study 6). Theoretical and managerial implications as well as future research opportunities are discussed.     

Researching self-help/mutual aid groups and organizations: Many roads, one journey

Self-help and mutual help groups are defined and the status of the literature described and reviewed. Self-help groups are different from peer and nonprofessional services under the supervision of professionals. Controlled studies of mutual help groups may be neither possible nor desirable as the method of choice by which to understand the phenomena of interest. Other approaches to research, including worldly evaluations, and ways of construing self-help organizations, that is, as normative communities and political action organizations rather than as psychological treatments, are discussed, and suggestions for future research are presented.     

Measuring implicit attitudes toward physical activity and sedentary behaviors: Test-retest reliability of three scoring algorithms of the Implicit Association Test and Single Category-Implicit Association Test

ObjectivesThe Implicit Association Test (IAT) and the Single-Category IAT (SC-IAT) are two frequently used measures of implicit attitudes. Nonetheless, the test-retest reliability of these measures has not been investigated. The aim of this study was to examine the test-retest reliability of a physical activity versus sedentary behavior IAT, a physical activity SC-IAT, and a sedentary behavior SC-IAT.MethodA total of 111 older adults living with chronic diseases were recruited. They either completed a physical activity versus sedentary behavior IAT (N = 54) or two independent SC-IATs of physical activity and sedentary behavior (N = 57). These tests were administered twice in a one-hour interval. Three scores were computed for each test (D-Score, DW-Score, IP-Score). Both absolute and relative test-retest reliability was computed.ResultsRegarding absolute reliability, the tests were comparable regardless of the scoring algorithm (Coefficients of Repeatability ranged from 1.27 for the two SC-IATs with the D-Score, to 1.36 for the IAT with the D-Score and DW-Score). Regarding relative test-retest reliability, the IAT systematically showed better reliability than the two SC-IATs. The DW-Score systematically exhibited better reliability compared to other scores (Intraclass Correlation Coefficient ranged from 0.20 for the sedentary behavior SC-IAT with the D-Score to 0.78 for the IAT with the DW-Score).ConclusionAdequate test-retest reliability for the IAT was supported independently from the scoring algorithms. Test-retest reliability for the two independent SC-IATs was not supported in this study. The IAT is more sensitive to change than the SC-IATs, which needs to be accounted for in future research on physical activity and sedentary behavior implicit attitudes.     

Unconscious processes influencing learning

This paper reviews recent experimental evidence on the active involvement of non-conscious processes in human functioning and examines the contribution of this evidence to understanding learning. The experimental concept of 'unconscious processing' is compared to the psychoanalytic notion of the 'unconscious' and some relationships between the two concepts are pointed out. The general idea stemming from experimental research is that, in parallel with what goes on at the conscious level, non-conscious dynamic processes have a very strong impact both in the process and the outcome of learning. Information, which in milliseconds is non-consciously assessed as threatening to the learner's psychological balance, may be disguised or blocked from further processing, therefore affecting the learner's educational competence. The educational material, relationship or atmosphere may provoke non-conscious emotions, attitudes and intentions, which 'inflate' cognition and can affect the individual's current processing of information in various (inhibiting or enhancing) ways. By carefully observing the points where the individual learner is blocked in the 'here and now', the teacher or therapist may deduce useful information on the issues that may unconsciously inhibit learning.     

Inclined to see it your way: Do altercentric intrusion effects in visual perspective taking reflect an intrinsically social process?

It has been suggested that some aspects of mental state understanding recruit a rudimentary, but fast and efficient, processing system, demonstrated by the obligatory slowing down of judgements about what the self can see when this is incongruent with what another can see. We tested the social nature of this system by investigating to what extent these altercentric intrusions are elicited under conditions that differed in their social relevance and, further, how these related to self-reported social perspective taking and empathy. In Experiment 1, adult participants were asked to make “self” or “other” perspective-taking judgements during congruent (“self” and “other” can see the same items) or incongruent conditions (“self” and “other” cannot see the same items) in conditions that were social (i.e., involving a social agent), semisocial (an arrow), or nonsocial (a dual-coloured block). Reaction time indices of altercentric intrusion effects were present across all conditions, but were significantly stronger for the social than for the less social conditions. Self-reported perspective taking and empathy correlated with altercentric intrusion effects in the social condition only. In Experiment 2, the significant correlations for the social condition were replicated, but this time with gaze duration indices of altercentric intrusion effects. Findings are discussed with regard to the degree to which this rudimentary system is socially specialized and how it is linked to more conceptual understanding.     

Stimulus–classification and stimulus–action associations: Effects of repetition learning and durability

It has been shown that acquired stimulus–response bindings result from at least two types of associations from the stimulus to the task (stimulus–task or stimulus–classification; S–C) and from the stimulus to the motor response (stimulus–response or stimulus–action; S–A). These types of associations have been shown to independently affect behaviour. This finding suggests that they are processed in different pathways or different parts of a pathway at the neural level. Here we test a hypothesis that such associations may be differentially affected by repetition learning and that such effects may be detected by measuring their durability against overwriting. We show that both S–C and S–A associations are in fact strengthened when learning is boosted by increasing repetitions of the primes. However, the results further suggest that associations between stimuli and actions have less durable effects on behaviour and that the durability of S–C and S–A associations is independent of repetition learning. This is an important finding for the understanding of the underlying mechanisms of associative learning and particularly raises the question of which processes may affect flexibility of learning.     

Action–perception coupling in pianists: Learned mappings or spatial musical association of response codes (SMARC) effect?

The principle of common coding suggests that a joint representation is formed when actions are repeatedly paired with a specific perceptual event. Musicians are occupationally specialized with regard to the coupling between actions and their auditory effects. In the present study, we employed a novel paradigm to demonstrate automatic action–effect associations in pianists. Pianists and nonmusicians pressed keys according to aurally presented number sequences. Numbers were presented at pitches that were neutral, congruent, or incongruent with respect to pitches that would normally be produced by such actions. Response time differences were seen between congruent and incongruent sequences in pianists alone. A second experiment was conducted to determine whether these effects could be attributed to the existence of previously documented spatial/pitch compatibility effects. In a “stretched” version of the task, the pitch distance over which the numbers were presented was enlarged to a range that could not be produced by the hand span used in Experiment 1. The finding of a larger response time difference between congruent and incongruent trials in the original, standard, version compared with the stretched version, in pianists, but not in nonmusicians, indicates that the effects obtained are, at least partially, attributable to learned action effects.     

Use of Anticipatory Cues to Reduce Dependence on Physical Prompts by an Adolescent with Multiple Disabilities

Anticipatory cues (vibratory stimulation activated through remote control) were used in this study to help an adolescent with multiple disabilities to reduce his dependence on the caregiver's physical prompts. The results show that anticipatory cues were effective in helping the adolescent perform practical daily responses independently of physical prompts. Towards the end of the study, the adolescent could also perform increasingly independently of the anticipatory cues. Implications of the findings are discussed.     

From left to right: Processing acronyms referring to names of political parties activates spatial associations

In line with previous studies, showing that abstract concepts like “power” or “god” implicitly activate spatial associations, in the present study we hypothesized that spatial associations are coactivated during the processing of acronyms referring to names of political parties as well. In four studies, it was found that the reading of these acronyms was accompanied by the implicit activation of spatial left–right associations. That is, participants responded faster to left-wing parties by means of a left-hand button press and vice versa for right-wing parties (Experiments 1 to 3), and participants responded faster when a political acronym was presented at the side of the screen corresponding to the political orientation of the acronym (Experiment 4). Interestingly, a correlation was observed between the effect size for left-wing parties and participants' political preferences, suggesting that the reaction time effects reflect the perceived distance of a party to one's own political orientation. Together these findings indicate that spatial representations activated in response to political acronyms do not simply reflect lexical–semantic associations or spatial metaphors, but representations of parties' political orientation relative to one's own sociopolitical position.
