Prior Attitudes,Salient Value Similarity,and Dimensionality: Toward an Integrative Model of Trust in Risk Regulation1

Although it is widely recognized that trust plays an important role in people's responses to various risks, there is still considerable conceptual disagreement about the different aspects of trust. There are at least 3 different approaches to trust: (a) dimensional, (b) salient value similarity, and (c) associationist. Three British datasets on genetically modified food were used to test the plausibility of a causal model that integrates these approaches. It appears that value similarity can be predicted by a combination of prior attitudes and perceived attitudes of the other, and that value similarity precedes other important trust judgments. The study suggests that various risk‐relevant judgments are expressions of a more general attitude toward genetically modified food, and raises questions about the usefulness of detailed modelling.     

Children retain implicitly learned phonological sequences better than adults: a longitudinal study

Whereas adults often rely on explicit memory, children appear to excel in implicit memory, which plays an important role in the acquisition of various cognitive skills, such as those involved in language. The current study aimed to test the assertion of an age‐dependent shift in implicit versus explicit learning within a theoretical framework that explains the link between implicit sequence memory and word‐form acquisition, using the Hebb repetition paradigm. We conducted a one‐year, multiple‐session longitudinal study in which we presented auditory sequences of syllables, co‐presented with pictures of aliens, for immediate serial recall by a group of children (8–9 years) and by an adult group. The repetition of one Hebb sequence was explicitly announced, while the repetition of another Hebb sequence was unannounced and, therefore, implicit. Despite their overall inferior recall performance, the children showed better offline retention of the implicit Hebb sequence, compared with adults who showed a significant decrement across the delays. Adults had gained more explicit knowledge of the implicit sequence than children, but this could not explain the age‐dependent decline in the delayed memory for it. There was no significant age‐effect for delayed memory of the explicit Hebb sequence, with both age groups showing retention. Overall performance by adults was positively correlated with measures of post‐learning awareness. Performance by children was positively correlated with vocabulary knowledge. We conclude that children outperform adults in the retention over time of implicitly learned phonological sequences that will gradually consolidate into novel word‐forms. The findings are discussed in the light of maturational differences for implicit versus explicit memory systems that also play a role in language acquisition.

Stuttering and anxiety: The difference between stutterers and nonstutterers in verbal apprehension and physiologic arousal during the anticipation of speech and non-speech tasks

To test if stressful anticipation of speech situations is a factor in eliciting stuttering behavior, the difference between 24 stutterers and 24 nonstutterers in verbal apprehension and physiologic activity was studied before and during speech tasks (reading and conversation), and nonspeech tasks (motor and intelligence task).Results indicate that the difference between stutterers and nonstutterers mainly were restricted to anxiety ratings assessed after each task. Heart rate, vasomotor responses, and electrodermal activity recorded before and during speech tasks were higher compared with the physiologic activity before and during nonspeech tasks but, unexpectedly, this was also the case for nonstutterers. It is concluded that stuttering is not elicited by anxiety.     

The orienting reaction during human eyelid conditioning following preconditioning exposures to the CS

Summary Two experiments on latent inhibition are described in which the electrodermal and alpha blocking components of the orienting reaction (OR) were measured during human eyelid conditioning. In the first experiment the 16 Ss in the experimental group received 20 CS pre-exposure trials. The OR habituated on those trials but reappeared fully after the first conditioning trial. Therefore, after that trial there was no difference in OR amplitude with a no pre-exposure control group. The two groups did not differ in conditioning performance either. In the second experiment two groups of 25 Ss received an equal number of CS pre-exposures but one group was conditioned during the performance of a masking task. This time the reappearance of the OR was only observed in the no-task group. The results of both experiments are discussed in relation to Sokolov's theory on the facilitative effect of the OR on conditioning.The author wishes to thank Ernest van Lieshout and Ad van Oirschot for running the experiments and for help in the data analysis     

What (not) to add in your ad: When job ads discourage older or younger job seekers to apply

Both older and younger job seekers face difficulties when entering the workforce. Qualification-based targeted recruitment (QBTR) might be used to attract older/younger job seekers, yet how this strategy is perceived by older/younger job seekers has not been considered before. The present study fills this gap and investigated effects of negatively metastereotyped information in job ads (i.e., personality requirements or traits) on application intention and self-efficacy of both older and younger job seekers. An experimental study (N_total = 556; 44.6% aged 50 or older, 55.4% aged 30 or younger) showed that negatively metastereotyped traits in job ads (e.g., “flexible”) lowered older job seekers’ application intention and that this effect was mediated by older job seekers’ self-efficacy regarding that trait. No such effects were found among younger job seekers. Results showed that organizations can fail to attract older candidates because of the traits mentioned in job ads, which is particularly alarming when aiming to target age-diverse applicants. Suggestions for practitioners and future research are formulated.     

Creativity Under Attack: How People’s Role in Competitive Conflict Shapes Their Creative Idea Generation

Although creativity is helpful if not needed to deal with conflicts, research on the effects of conflict on creativity shows inconsistent findings. In this study, the possibility that effects may depend on people’s role in conflict was considered. Whether, when, and why assuming the role of attacker or defender in conflict affects creative idea generation was therefore investigated. The prediction was tested if attackers are more creative than defenders. In addition, control over the situation as a moderating variable and anxiety as a mediator were considered. Participants (n = 115, M_age = 22.06, SD_age = 2.75, 83 women) were recruited in Amsterdam, the Netherlands, and were randomly assigned to an attacker, defender, or role control condition. Controllability over the situation was manipulated within-subjects and anxiety and creativity were measured during 2 rounds of idea generation. Results revealed no differences in creative performance and anxiety between defenders and attackers and that defenders generated a greater number of ideas than people in the role control condition. Exploratory analyses further revealed that attackers and defenders generated a greater number of aggressive ideas. Finally, attackers and defenders experienced more anxiety, but increased anxiety did not account for observed differences in the number of (aggressive) ideas. The effect of controllability could not be investigated due to a failed manipulation. Limitations and implications are discussed.     

The Hebb repetition effect as a laboratory analogue of novel word learning

The present study tests the hypothesis that a common ordering mechanism underlies both short-term serial recall of verbal materials and the acquisition of novel long-term lexical representations, using the Hebb repetition effect. In the first experiment, participants recalled visually presented nonsense syllables following a typical Hebb effect learning protocol. Replicating the Hebb repetition effect, we observed improved recall for repeated sequences of syllables. In the second experiment, the same participants performed an auditory lexical decision task, which included nonwords that were constructed from the syllables used in the first experiment. We observed inhibited rejection of nonwords that were composed of the repeated Hebb sequences, compared to nonwords that were built from nonrepeated filler sequences. This suggests that a long-term phonological lexical representation developed during Hebb learning. Accordingly, the relation between immediate serial recall and word learning is made explicit by arguing that the Hebb repetition effect is a laboratory analogue of naturalistic vocabulary acquisition.     

One, two, three, many - Subitizing in active touch

‘Subitizing’ refers to rapid and accurate judgement of small numbers of items, while response times and error rates increase rapidly for larger set-sizes. Most enumeration studies have been done in vision. Enumeration studies in touch have mostly involved ‘passive touch’, i.e. touch without active exploration. In daily life a much more common situation is that of ‘active touch’, e.g. when we count the number of coins in our pocket. To investigate numerosity judgement in active touch, we let subjects haptically explore varying numbers of spheres. Our results show that enumeration for up to 3 items is more efficient than for larger numbers of items. We also show that enumeration in this regime was not performed through estimation. Furthermore, it is shown that numerosity information was accessed directly and not through mass or volume cues. Not only do our results show that a haptic version of subitizing exists in active touch, they also suggest similar underlying enumeration mechanisms across different modalities.
