Although domestic dogs can respond to many facial cues displayed by other dogs and humans, it remains unclear whether they
can differentiate individual dogs or humans based on facial cues alone and, if so, whether they would demonstrate the face
inversion effect, a behavioural hallmark commonly used in primates to differentiate face processing from object processing.
In this study, we first established the applicability of the visual paired comparison (VPC or preferential looking) procedure
for dogs using a simple object discrimination task with 2D pictures. The animals demonstrated a clear looking preference for
novel objects when simultaneously presented with prior-exposed familiar objects. We then adopted this VPC procedure to assess
their face discrimination and inversion responses. Dogs showed a deviation from random behaviour, indicating discrimination
capability when inspecting upright dog faces, human faces and object images; but the pattern of viewing preference was dependent
upon image category. They directed longer viewing time at novel (vs. familiar) human faces and objects, but not at dog faces,
instead, a longer viewing time at familiar (vs. novel) dog faces was observed. No significant looking preference was detected
for inverted images regardless of image category. Our results indicate that domestic dogs can use facial cues alone to differentiate
individual dogs and humans and that they exhibit a non-specific inversion response. In addition, the discrimination response
by dogs of human and dog faces appears to differ with the type of face involved. 相似文献

Accumulating evidence suggests that emotional information is often recognised faster than neutral information. Several studies examined the effects of valence and arousal on word recognition, but yielded partially diverging results. Here, we used two alternative versions of a constructive recognition paradigm in which a target word is hidden by a visual mask that gradually disappears, to investigate whether the emotional properties of words influence their speed of recognition. Participants were instructed either to classify the incrementally appearing word as emotional or non-emotional (semantic categorisation task) or to decide whether the appearing letter string is an existing word or not (lexical decision task). Results from both tasks revealed faster recognition times for high- compared to low-arousing words, and for positive compared to negative or neutral words. These findings indicate a recognition advantage for emotionally positive and highly arousing stimuli that persists even when visual word recognition is hampered and participants are encouraged to make more active, semantic inferences to generate the meaning of the emerging word. 相似文献

A fine-grained dual-process approach to conditional reasoning is advocated: Responses to conditional syllogisms are reached through the operation of either one of two systems, each of which can rely on two different mechanisms. System1 relies either on pragmatic implicatures or on the retrieval of information from semantic memory; System2 operates first through inhibition of System1, then (but not always) through activation of analytical processes. It follows that reasoners will fall into one of four groups of increasing reasoning ability, each group being uniquely characterized by (a) the modal pattern of individual answers to blocks of affirming the consequent (AC), denying the antecedent (DA), and modus tollens (MT) syllogisms featuring the same conditional; and (b) the average rate of determinate answers to AC, DA, and MT. This account receives indirect support from the extant literature and direct support from a mixed Rasch model of responses given to 18 syllogisms by 486 adult reasoners. 相似文献

People tend to perceive identical top halves (i.e. above the nose) of two face stimuli as being different when they are aligned with distinct bottom halves. This composite face illusion is generally considered as the most compelling evidence that facial features are integrated into a holistic representation. Here, we recorded eye‐movements during the composite face illusion in a delayed matching task of top halves of faces. Behavioural results showed a strong composite face effect, participants making more mistakes and taking longer time to match two identical top halves of faces when they were aligned (vs. misaligned) with different bottom halves. Importantly, fixation sites and eye‐movements were virtually identical when the top and bottom parts were aligned (composite illusion) or misaligned (no illusion), indicating that holistic face processing can be independent of gaze behaviour. These findings reinforce the view that holistic representations of individual faces can be extracted early on from information at a relatively coarse scale, independently of overt attention. 相似文献

Relatively few studies have examined memory bias for social stimuli in depression or dysphoria. The aim of this study was to investigate the influence of depressive symptoms on memory for facial information. A total of 234 participants completed the Beck Depression Inventory II and a task examining memory for facial identity and expression of happy and sad faces. For both facial identity and expression, the recollective experience was measured with the Remember/Know/Guess procedure (Gardiner & Richardson-Klavehn, 2000). The results show no major association between depressive symptoms and memory for identities. However, dysphoric individuals consciously recalled (Remember responses) more sad facial expressions than non-dysphoric individuals. These findings suggest that sad facial expressions led to more elaborate encoding, and thereby better recollection, in dysphoric individuals. 相似文献

Laterality is now known to be an ubiquitous phenomenon among the vertebrates. Particularly, laterality of auditory processing
has been demonstrated in a variety of species, especially songbirds and primates. Such a hemispheric specialization has been
shown to depend on factors such as sound structure, species specificity and types of stimuli. Much less is known on the possible
influence of social familiarity although a few studies suggest such an influence. Here we tested the influence of the degree
of familiarity on the laterality of the auditory response in the domestic horse. This species is known for its social system
and shows visible reactions to sounds, with one or two ears moving towards a sound source. By comparing such responses to
the playback of different conspecific whinnies (group member, neighbor and stranger), we could demonstrate a clear left hemisphere
(LH) preference for familiar neighbor calls while no preference was found for group member and stranger calls. Yet, we found
an opposite pattern of ear side preference for neighbor versus stranger calls. These results are, to our knowledge, the first
to demonstrate auditory laterality in an ungulate species. They open further lines of thought on the influence of the social
“value” of calls and the listener’s arousal on auditory processing and laterality. 相似文献

ObjectiveThis study investigated girls' endorsement of the stereotype that girls are not good soccer performers through three questions: (1) did stereotype endorsement predict soccer performance? (2) Was this relationship mediated by perceived ability? (3) Was stereotype endorsement related to gender role orientation?MethodOne hundred and two junior high school girls from the 6th to the 9th grade (M age = 13.5 years, SD = 1.23) reported their beliefs about girls' and boys' performance in soccer, perceived ability and gender role orientation. Next, their soccer performance was observed during matches in compulsory physical education classes. A path-analytic model tested the relationships among the variables using a product-moment correlation matrix and a maximum likelihood estimation procedure.ResultsStereotype endorsement (i.e., the belief that girls' performance in soccer is poor) negatively predicted performance, this relationship being mediated by perceived ability. Moreover, masculinity positively predicted perceived ability, and this relationship was partially mediated by stereotype endorsement.ConclusionThis study reinforces the idea that girls' sports performance may be related to gender stereotypes. Interpretations of the results in light of Eccles et al.’s expectancy-value model and stereotype threat theory are discussed, along with implications for practice. 相似文献

Saffran, Newport, and Aslin (1996a) found that human infants are sensitive to statistical regularities corresponding to lexical units when hearing an artificial spoken language. Two sorts of segmentation strategies have been proposed to account for this early word-segmentation ability: bracketing strategies, in which infants are assumed to insert boundaries into continuous speech, and clustering strategies, in which infants are assumed to group certain speech sequences together into units ( Swingley, 2005 ). In the present study, we test the predictions of two computational models instantiating each of these strategies i.e., Serial Recurrent Networks: Elman, 1990 ; and Parser: Perruchet & Vinter, 1998 in an experiment where we compare the lexical and sublexical recognition performance of adults after hearing 2 or 10 min of an artificial spoken language. The results are consistent with Parser's predictions and the clustering approach, showing that performance on words is better than performance on part-words only after 10 min. This result suggests that word segmentation abilities are not merely due to stronger associations between sublexical units but to the emergence of stronger lexical representations during the development of speech perception processes. 相似文献
