Grasp preparation improves change detection for congruent objects

A series of experiments provided converging support for the hypothesis that action preparation biases selective attention to action-congruent object features. When visual transients are masked in so-called change-blindness scenes, viewers are blind to substantial changes between 2 otherwise identical pictures that flick back and forth. The authors report data in which participants planned a grasp prior to the onset of a change-blindness scene in which 1 of 12 objects changed identity. Change blindness was substantially reduced for grasp-congruent objects (e.g., planning a whole-hand grasp reduced change blindness to a changing apple). A series of follow-up experiments ruled out an alternative explanation that this reduction had resulted from a labeling or strategizing of responses and provided converging support that the effect genuinely arose from grasp planning.     

Knowledge of Language Transfers From Speech to Sign: Evidence From Doubling

Does knowledge of language transfer across language modalities? For example, can speakers who have had no sign language experience spontaneously project grammatical principles of English to American Sign Language (ASL) signs? To address this question, here, we explore a grammatical illusion. Using spoken language, we first show that a single word with doubling (e.g., trafraf) can elicit conflicting linguistic responses, depending on the level of linguistic analysis (phonology vs. morphology). We next show that speakers with no command of a sign language extend these same principles to novel ASL signs. Remarkably, the morphological analysis of ASL signs depends on the morphology of participants' spoken language. Speakers of Malayalam (a language with rich reduplicative morphology) prefer XX signs when doubling signals morphological plurality, whereas no such preference is seen in speakers of Mandarin (a language with no productive plural morphology). Our conclusions open up the possibility that some linguistic principles are amodal and abstract.     

The Impact of Participating in Suicide Research Online

The impact of participation in online mixed‐methods suicide research was investigated. Participants, who described feeling suicidal, completed an 18‐item questionnaire before and after taking part (n = 103), and answered open‐ended questions about participation (n = 97). Overall, participation reduced negative experiences and had no effect on positive experiences. Feelings of calm increased, but participants felt less supported. Some participants did experience distress, but some also reported this distress to be manageable. Anonymously sharing experiences of suicidality was viewed as important, had therapeutic benefits, and engendered hopes for recovery. The findings suggest a need to ensure vulnerable participants in online studies are well supported while protecting their anonymity.     

On Faith,Merit, and Eternal Life

Can eternal life be merited? The traditional Lutheran answer to this question has been negative. However, the question is not as simple as it first seems. For example, recently, Mats Wahlberg has argued that Lutherans should admit that eternal life can be merited, especially if they support the “Finnish Luther interpretation.” Although I find much to commend in Wahlberg's reading, there are at least two problems in his proposal. First, the language of merit is tied to a particular philosophical framework that is not shared ecumenically; and second, all Lutherans do not share all the details of the Finnish reading of Luther. However, both Wahlberg's proposal and the Finnish interpretation of Luther have genuine ecumenical potential if they are developed so that they can address the concerns related to the philosophy of action and Christian life.     

The role of visual attention in action priming

It has been demonstrated that the task-irrelevant left-right orientation of an object is capable of facilitating left-right-hand responses when the object is orientated towards the responding hand. We investigated the role of attention in this orientation effect. Experiment 1 showed that object orientation facilitates responses of the hand that is compatible with the object's orientation, despite the entire object being irrelevant. However, when a task-relevant fixation point was displayed over the prime object in Experiment 2, the effect was not observed. Together Experiments 1 and 2 suggest that the orientation information of viewed objects primes the action selection processes even when the object is irrelevant, but only when attention is not allocated to a competing stimulus during the prime presentation. Experiment 3 suggested that the elimination of the effect in Experiment 2 could not be attributed to the elimination of an attentional shift to the graspable part of the prime. Finally, Experiment 4 showed that object orientation can evoke an abstract response code, influencing the selection of finger responses.     

The threat simulation theory of the evolutionary function of dreaming: Evidence from dreams of traumatized children

The threat simulation theory of dreaming (TST) () states that dream consciousness is essentially an ancient biological defence mechanism, evolutionarily selected for its capacity to repeatedly simulate threatening events. Threat simulation during dreaming rehearses the cognitive mechanisms required for efficient threat perception and threat avoidance, leading to increased probability of reproductive success during human evolution. One hypothesis drawn from TST is that real threatening events encountered by the individual during wakefulness should lead to an increased activation of the system, a threat simulation response, and therefore, to an increased frequency and severity of threatening events in dreams. Consequently, children who live in an environment in which their physical and psychological well-being is constantly threatened should have a highly activated dream production and threat simulation system, whereas children living in a safe environment that is relatively free of such threat cues should have a weakly activated system. We tested this hypothesis by analysing the content of dream reports from severely traumatized and less traumatized Kurdish children and ordinary, non-traumatized Finnish children. Our results give support for most of the predictions drawn from TST. The severely traumatized children reported a significantly greater number of dreams and their dreams included a higher number of threatening dream events. The dream threats of traumatized children were also more severe in nature than the threats of less traumatized or non-traumatized children.     

Changes in studying abilities as perceived by students attending psychotherapy

In rehabilitative psychotherapy, the goal is to support and improve the person's working and studying capacity and to secure his/her staying in or entering the workforce. In this qualitative study, the aim was to describe the changes students experienced in their studying ability and the advancement of their studies as a result of the therapy process. The results of this study showed many kinds of positive changes in the psychological resources and studying ability of students participating in psychotherapy. The results also show that when psychotherapy is arranged with the aim to support the study process, good connections between psychotherapy, study tutoring and career guidance are needed.     

IMAGO DEI AND HUMAN RATIONALITY

There is a pervasive trend in Western theology to identify imago Dei with human intellectual and cognitive capacities. However, several contemporary theologians have criticized this view because, according to the critics, it leads to a truncated view of humanity. In this article, I shall concentrate on the question of rationality, first, through theologies of Thomas Aquinas and contemporary Lutheran Robert Jenson, and second, in some branches of recent cognitive psychology. I will argue that there is a significant overlap between contemporary scientific interpretations of rationality and both a traditional Thomistic view and a contemporary ecumenical interpretation of imago Dei. Consequently, it is possible to give an account of imago Dei which takes structural features as central and which is in accord with contemporary science, without falling prey to the dangers that the critics of structuralism point out.     

Mapping the identity of a viewed hand in the motor system: evidence from stimulus-response compatibility

Brain-imaging research has shown that a viewed acting hand is mapped to the observer's hand representation that corresponds with the identity of the hand. In contrast, behavioral research has suggested that rather than representing a seen hand in relation to one's own manual system, it is represented in relation to the midline of an imaginary body. This view was drawn from the finding that indicated that the posture of the viewed hand determines how the hand facilitates responses. The present study explored how an identity of a viewed static hand facilitates responses by varying the onset time and the posture of the hand. The results were in line with the view that an observed hand can activate the observer's hand representation that corresponds with the identity of the hand. However, the posture of the hand did not influence these mapping processes. What mattered was the perspective (i.e., egocentric vs. allocentric) from which the hand was viewed.
