Reactivity and response to pain

Male and female volunteers (N = 144) answered the Reactivity Scale (RS) and underwent testing for their perceived intensity and tolerance for finger-pressure pain. Half the Ss were randomly assigned to a low-intensity treatment (1150 g) and half to a high-intensity treatment (2300 g). Pain was rated at 30 and 60 sec., and Ss were asked to endure it as long as possible up to 5 min. The major findings were as follows: (1) women outscored men on reactivity; (2) the three pain measures intercorrelated highly; (3) high-intensity stimulation produced higher pain ratings and shorter tolerance than did low-intensity stimulation; (4) men gave lower intensity ratings than women and tolerated the pain longer; (5) reactivity related positively to judged pain at 30 and 60 sec, and negatively to pain tolerance; (6) there were no significant interaction effects among stimulus intensity, sex and reactivity for any pain measure; (7) the variance in the pain measures accounted for by stimulus intensity, sex and reactivity ranged from 26 to 32%. The implications were briefly discussed for the validity of the RS and factors explaining responses to experimentally-induced pain.     

Extending the Basic Local Independence Model to Polytomous Data

Psychometrika - A probabilistic framework for the polytomous extension of knowledge space theory (KST) is proposed. It consists in a probabilistic model, called polytomous local independence model,...     

Coping with Age‐related Threats to Role Identity: Older Couples and the Management of Household Money

As more couples live together into old age, difficult decisions have to be made about money matters, including the financing of late‐life care. This paper analyses in‐depth qualitative data from six older heterosexual couples, part of a wider study concerning money management in later life. Research when these cohorts were younger found that the organisation of money management within households was specialised and highly gendered, leading to substantive imbalances of power and access to financial resources, while also being core to the formation and maintenance of gendered role identities and couple identities. We find in this study that if a partner's ability to fulfil a money management role identity is threatened by later‐life issues such as poor health and cognitive decline, the other partner may try to protect that aspect of the spouse's role identity, using various covert strategies. This might be done to shore up the spouse's self‐esteem in the face of such age‐related threats to role identity, to ‘keep up appearances’ to the outside world or to maintain their identity as a couple at a time of life when there may be multiple difficulties to deal with. These findings have implications for practice and policy in the realm of money and identity management in later life. Copyright © 2013 John Wiley & Sons, Ltd.     

Resiliency in Families with a Member with a Psychological Disorder

The aim of this study was to identify resiliency factors in families with a mentally ill family member. The study population was composed of 30 families, where questionnaires were independently completed by both a parent and a child. The results indicate that family hardiness was an important resilience factor for both the parents and the children. According to the parents the passive evaluation of a crisis situation, or the use of avoidance strategies, was also helpful for the family to adapt. For the children, the extent to which they found support from within the community and the extent to which they experienced emotional support, self-worth, and community support were linked to their view on family adaptation to stressful situations.     

Evaluative Conditioning Is a Form of Associative Learning: On the Artifactual Nature of Field and Davey's (1997) Artifactual Account of Evaluative Learning

Field and Davey (1997) claimed that evaluative conditioning (EC), rather than being a genuine type of Pavlovian associative learning, represents nothing but an experimental artifact. They come to this conclusion by first identifying the prototypical experimental procedure of EC research, by next pointing to the potential methodological shortcomings of this prototypical procedure in order to infer associative learning, and by finally demonstrating that when the appropriate controls are added to this prototypical procedure, it becomes clear that apparent EC results represent nothing but an experimental artifact. In this paper, we first demonstrate that what Field and Davey identify as the “prototypical procedure” is, as a matter of fact, the exception rather than the rule in EC research, such that the potential scope of their criticism is rather limited. Next, we show how the results of their own experiment are actually due to an artifact that is not present in any EC study. Finally, we discuss how Field and Davey's criticism of EC research has its roots in a misconception of the appropriate within or between subject controls for Pavlovian associative learning.     

Procedural Multimedia Presentations: The Effects of Working Memory and Task Complexity on Instruction Time and Assembly Accuracy

Procedural text conveys information of a series of steps to be performed. This study examined the role of verbal and visuo‐spatial WM in comprehension and execution of assembly instructions, as a function of format (text, images, multimedia) and task complexity (three or five steps). One hundred and eight participants read and executed 27 instructions to assemble a LEGO^TM object, in single and dual task conditions. Study times and errors during assembly were measured. Participants processed faster pictorial and multimedia instructions than text instructions, and made fewer errors in the execution of multimedia instructions. Dual task affected more text or picture‐only, than multimedia presentation. A verbal secondary task caused more errors in text or picture‐only presentations, and spatial secondary task also caused interference in text‐only instructions. Overall, these results support the multimedia advantage, and the role of both verbal and visuo‐spatial WM, when understanding instructions. Copyright © 2016 John Wiley & Sons, Ltd.     

The Role of the Listener on the Emotional Valence of Personal Memories in Emerging Adulthood

Many scholars stressed the role of social interactions in the construction of autobiographical memories, especially in late adolescence and emerging adulthood. This paper aims to assess the impact of the listener attitude on narrator’s emotional valence of past life events concerning the end of a close relationship. 157 emerging adults have been asked to recall a memory and to randomly narrate it to a listener previously trained to be distracted and detached (DL group) versus attentive and empathic (AL group). A control group (CG) had only to reflect internally on the recalled memory. Participants had to allocate one or more emotions to their memory from a 12-item list in a recall task, a narrative/reflection task and a 15-day recall follow-up. The percentages of negative, positive and neutral emotions were assessed and changes among the three emotional allocations were measured. Results showed that participants of the AL group after the narrative task increased the positive emotional engagement of memories and decreased the negative emotions in comparison to DL participants and the CG ones. The authors interpret the results suggesting that narrating autobiographical memories to attentive peers is a way to co-construct their emotional meaning and discuss findings in the light of the knowledge on the lifespan period of emerging adulthood.     

A class of k-modes algorithms for extracting knowledge structures from data

One of the most crucial issues in knowledge space theory is the construction of the so-called knowledge structures. In the present paper, a new data-driven procedure for large data sets is described, which overcomes some of the drawbacks of the already existing methods. The procedure, called k-states, is an incremental extension of the k-modes algorithm, which generates a sequence of locally optimal knowledge structures of increasing size, among which a “best” model is selected. The performance of k-states is compared to other two procedures in both a simulation study and an empirical application. In the former, k-states displays a better accuracy in reconstructing knowledge structures; in the latter, the structure extracted by k-states obtained a better fit.
