Domestic dogs comprehend human communication with iconic signs

A key skill in early human development is the ability to comprehend communicative intentions as expressed in both nonlinguistic gestures and language. In the current studies, we confronted domestic dogs (some of whom knew many human ‘words’) with a task in which they had to infer the intended referent of a human's communicative act via iconic signs – specifically, replicas and photographs. Both trained and untrained dogs successfully used iconic replicas to fetch the desired item, with many doing so from the first trial. Dogs’ ability to use photographs in this same situation was less consistent. Because simple matching to sample in experimental contexts typically takes hundreds of trials (and because similarity between iconic sign and target item did not predict success), we propose that dogs’ skillful performance in the current task reflects important aspects of the comprehension of human communicative intentions.     

Is a Stage Model a Useful Approach to Explain Car Drivers' Willingness to Use Public Transportation?

The paper empirically evaluates the utility of a stage approach in describing car drivers' decisions to change to public transportation. Data from 2 samples are used to test whether 5 subgroups assumed to represent an ordered sequence of decision stages derived from an extended version of the model of action phases ( Gollwitzer, 1996 ) is clearer than the changed one. Contrary to expectations, cluster analysis indicates that a 4-cluster solution is most adequate. Whereas the profiles of 3 clusters fit the expected features of the precontemplation, contemplation, and maintenance stages, the existence of separated preparation and action stages was not confirmed. Evidence was also mixed for the assumption that the assignment to the decision stages can be predicted by specific motivational variables.     

Word form access dyslexia: understanding the basis of visual reading errors

We report the case of a patient V.E.M. who exhibits the infrequently described syndrome of visual dyslexia. V.E.M. read many single words accurately and rapidly; however, when words were read inaccurately, the majority of responses were alternate real words bearing a strong visual relationship to the target items. A series of observational and experimental investigations of her reading skills revealed that response accuracy was strongly affected by word frequency and mildly affected by concreteness but not influenced by word length, orthographic neighbourhood size, or semantic priming. It is argued that V.E.M.'s visual dyslexia results from a deficit of the visual word form system. More specifically, we propose that this deficit has an “access” quality, with visual word form representations remaining relatively intact despite an impairment in the processes by which these representations are activated. Taking the results of this study together with previous reports of dyslexic patients who make a high proportion of visual paralexic errors, we also suggest that visual dyslexia represents a multicomponent dyslexic syndrome for which phonological impairment and not semantic impairment may be a necessary condition.     

Think manager—think male,think follower—think female: Gender bias in implicit followership theories

Because of the overlap between the social roles of women and followers, we predicted that people would show a bias, that is, favor female followers over male followers. To support this hypothesis, we conducted two studies: An explicit test of the bias using a scenario design and an implicit association test (IAT)‐based study. Both studies show that the role of an ideal follower is more strongly associated with the female gender role, which seems to be caused partly by a more communal connotation of the follower role. This effect might contribute to the underrepresentation of women in leadership positions as they are perceived to be an ideal fit for followership positions; but it may also push men away from being followers and into leadership positions.     

Abstract Conceptual Feature Ratings Predict Gaze Within Written Word Arrays: Evidence From a Visual Wor(l)d Paradigm

The Abstract Conceptual Feature (ACF) framework predicts that word meaning is represented within a high‐dimensional semantic space bounded by weighted contributions of perceptual, affective, and encyclopedic information. The ACF, like latent semantic analysis, is amenable to distance metrics between any two words. We applied predictions of the ACF framework to abstract words using eyetracking via an adaptation of the classical “visual word paradigm” (VWP). Healthy adults (n = 20) selected the lexical item most related to a probe word in a 4‐item written word array comprising the target and three distractors. The relation between the probe and each of the four words was determined using the semantic distance metrics derived from ACF ratings. Eye movement data indicated that the word that was most semantically related to the probe received more and longer fixations relative to distractors. Importantly, in sets where participants did not provide an overt behavioral response, the fixation rates were nonetheless significantly higher for targets than distractors, closely resembling trials where an expected response was given. Furthermore, ACF ratings which are based on individual words predicted eye fixation metrics of probe‐target similarity at least as well as latent semantic analysis ratings which are based on word co‐occurrence. The results provide further validation of Euclidean distance metrics derived from ACF ratings as a measure of one facet of the semantic relatedness of abstract words and suggest that they represent a reasonable approximation of the organization of abstract conceptual space. The data are also compatible with the broad notion that multiple sources of information (not restricted to sensorimotor and emotion information) shape the organization of abstract concepts. While the adapted “VWP” is potentially a more metacognitive task than the classical visual world paradigm, we argue that it offers potential utility for studying abstract word comprehension.     

Understanding the Development of Team Identification: A Qualitative Study in UN Peacebuilding Teams

Purpose

The goal of our study was to scrutinize the psychological processes that occur in individuals when developing identification with a highly diverse team.

Design/Methodology/Approach

A qualitative, theory-generating approach following the principles of grounded theory was chosen as research design. Data were obtained from 63 personal interviews with members of seven UN peacebuilding teams in Liberia and Haiti. These teams were particularly well suited for analyzing the dynamics of identification processes as they constitute extreme cases with respect to team members’ identity diversity.

Findings

Our analysis reveals four different processes that occur as individuals develop team identification (TI): enacting a salient identity, sensemaking about team experience, evaluating collective team outcomes, and converging identity.

Implications

We can show that team members engage in both individual- and collective-directed sensemaking processes during TI development, thereby using internal (i.e., other team members) and external points of reference (i.e., team-external actors) for ingroup/outgroup comparisons. Moreover, our study reveals different modes of identity convergence (i.e., active, reactive, and withdrawal) which are associated with different types of TI (i.e., deep-structured TI, situated TI, and disidentification).

Originality/Value

Although team members’ identification with their workgroup has long been considered important for effective team functioning, knowledge about its development has remained limited and largely without empirical footing from a real-world team context. Our study represents the first empirical attempt to inductively identify the processes that occur in individuals as they develop TI.

     

McGurk stimuli for the investigation of multisensory integration in cochlear implant users: The Oldenburg Audio Visual Speech Stimuli (OLAVS)

The concurrent presentation of different auditory and visual syllables may result in the perception of a third syllable, reflecting an illusory fusion of visual and auditory information. This well-known McGurk effect is frequently used for the study of audio-visual integration. Recently, it was shown that the McGurk effect is strongly stimulus-dependent, which complicates comparisons across perceivers and inferences across studies. To overcome this limitation, we developed the freely available Oldenburg audio-visual speech stimuli (OLAVS), consisting of 8 different talkers and 12 different syllable combinations. The quality of the OLAVS set was evaluated with 24 normal-hearing subjects. All 96 stimuli were characterized based on their stimulus disparity, which was obtained from a probabilistic model (cf. Magnotti & Beauchamp, 2015). Moreover, the McGurk effect was studied in eight adult cochlear implant (CI) users. By applying the individual, stimulus-independent parameters of the probabilistic model, the predicted effect of stronger audio-visual integration in CI users could be confirmed, demonstrating the validity of the new stimulus material.     

Loneliness and psychological health of orthopaedic patients’ caregivers: does gender make a difference?

Although research evidence indicates that loneliness is detrimental to mental health in diverse populations, impact of loneliness on psychological distress of orthopaedic patients’ caregivers has been given little research attention. The present study examined the association of loneliness with psychological health, and explored gender differences in the loneliness and psychological health association among orthopaedic patients’ caregivers. Participants were 250 patients’ caregivers drawn from a national orthopaedic hospital in eastern Nigeria. Data was collected by means of self-report measures translated into the local dialect of the caregivers. Multiple regression results showed that loneliness positively predicted psychological distress in the total sample. Loneliness did not predict psychological distress of male caregivers, but it positively predicted psychological distress of female caregivers. In order to promote orthopaedic patients caregivers’ mental health, gender-based differentials in the link between loneliness and psychological distress should be addressed by researchers and healthcare practitioners.     

Verbesserung psychischer Allgemeinfunktionen durch Psychotherapie

Zusammenfassung  Im Rahmen einer bundesweiten Fragebogenuntersuchung, die eine systematische Replikation der 1994 in den USA durchgeführten Consumer-Reports-Study für Deutschland darstellte, wurden mit Hilfe des ins Deutsche übersetzten Originalfragebogens Psychotherapiepatienten, u. a. nach einer Verbesserung der Zielsymptomatik sowie nach Veränderungen unspezifischer psychischer Allgemeinfunktionen, wie Beziehungsfähigkeit, Arbeitsfähigkeit, Fähigkeit zur Stressbewältigung, körperliches Wohlbefinden, Lebensfreude, persönliche Entwicklung, Verständnis für andere, Selbstwertgefühl und Stimmungslage, durch die Behandlung befragt. Bei der Auswertung der Antworten zeigte sich, dass eine psychotherapeutische Behandlung nicht nur zu einer deutlichen Symptombesserung, sondern auch zu einer Besserung dieser unspezifischen psychischen Allgemeinfunktionen führt. Und je länger die Behandlung erfolgt war, desto größer fielen die Besserungsraten aus. Der Vergleich der unterschiedlichen psychotherapeutischen Verfahren offenbarte marginale Unterschiede zwischen Psychoanalyse, tiefenpsychologisch-fundierter Psychotherapie und Verhaltenstherapie.

Activation of midbrain structures by associative novelty and the formation of explicit memory in humans

Recent evidence suggests a close functional relationship between memory formation in the hippocampus and dopaminergic neuromodulation originating in the ventral tegmental area and medial substantia nigra of the midbrain. Here we report midbrain activation in two functional MRI studies of visual memory in healthy young adults. In the first study, participants distinguished between familiar and novel configurations of pairs of items which had been studied together by either learning the location or the identity of the items. In the second study, participants studied words by either rating the words' pleasantness or counting syllables. The ventral tegmental area and medial substantia nigra showed increased activation by associative novelty (first study) and subsequent free recall performance (second study). In both studies, this activation accompanied hippocampal activation, but was unaffected by the study task. Thus midbrain regions seem to participate selectively in hippocampus-dependent processes of associative novelty and explicit memory formation, but appear to be unaffected by other task-relevant aspects.
