In the study of human behaviour, non-social targets are often used as a control for human-to-human interactions. However, the concept of anthropomorphisation suggests that human-like qualities can be attributed to non-human objects. This can prove problematic in psychological experiments, as computers are often used as non-social targets. Here, we assessed the degree of computer anthropomorphisation in a sequential and iterated prisoner’s dilemma. Participants (N = 41) faced three opponents in the prisoner’s dilemma paradigm—a human, a computer, and a roulette—all represented by images presented at the commencement of each round. Cooperation choice frequencies and transition probabilities were estimated within subjects, in rounds against each opponent. We found that participants anthropomorphised the computer opponent to a high degree, while the same was not found for the roulette (i.e. no cooperation choice difference vs human opponents; p = .99). The difference in participants’ behaviour towards the computer vs the roulette was further potentiated by the precedent roulette round, in terms of both cooperation choice (61%, p = .007) and cooperation probability after reciprocated defection (79%, p = .007). This suggests that there could be a considerable anthropomorphisation bias towards computer opponents in social games, even for those without a human-like appearance. Conversely, a roulette may be a preferable non-social control when the opponent’s abilities are not explicit or familiar.

Recent research has examined the sexualization–objectification link (i.e. whether sexualized individuals are appraised as if they were objects rather than persons). This research has found that sexualized individuals are more likely to be processed and categorized as if they were objects and are also perceived as possessing fewer humanlike traits than nonsexualized individuals. In addition, sexualization prompts negative behaviors such as social exclusion. Altogether, these findings shed light on mechanisms that might underlie violence toward sexualized individuals., info:eu-repo/semantics/published

Using a mouse-tracking technique, we measured the strength and the temporal unfolding of the conflict when people categorize objectified and nonobjectified human stimuli in the human or object category. We recorded participants’ hand movements when they categorized male and female, objectified and nonobjectified, human, and doll-like stimuli in the person and object categories. As expected, objectified women created a stronger categorization conflict compared to all other human stimuli. The nature of the mouse trajectories indicated that this response competition was caused by the distractor (object category) rather than the target (person category) and showed to be smooth rather than abrupt suggesting dynamic competition between the object–human categories rather than the sequential unfolding of a dual process. These findings demonstrate that the human–object divide fades when women (but not men) are objectified. The implications of the current findings for theorizing on processes of sexual objectification are discussed.

Extensive experimental research has been conducted to investigate how individuals empathise with others depending on contextual and motivational factors. However, the effect of sexual objectification (i.e. focus on the individual's physical appearance over his/her mental state) on empathy is scarce at best thus far. The aim of this work is to shed light on whether objectification modulates empathic responses toward humans and human-like objects. In Experiment 1, participants either underwent visuo-tactile stimulation or witnessed another person (a mannequin, a sexualized or a non-sexualized female confederate) being stimulated with pleasant or unpleasant objects. Participants were then asked to report either their own or the other's emotional experience. Results showed that shared representations (i.e. similarity between self-other emotional ratings) are significantly lower for the mannequin, intermediate for the sexualized woman, and reach the highest values for the non-sexualized woman. In Experiment 2, shared representations were assessed during a ball-tossing game in which the participants or one of the two confederates (sexualized or non-sexualized woman) were excluded from the game. Again, results showed reduced similarity between self-other emotional ratings toward sexualized as compared to non-sexualized women. The findings suggest that interacting with sexually objectified women reduces empathic responses typically observed within human relations.

Objectification – reducing a someone to a something – represents a powerful and potentially damaging way in which we can see and treat others. Women are often victims of processes of objectification that occur whenever a woman is reduced to her body or certain body parts. What remains unclear is the extent to which a woman becomes an object when objectified. Using the oddball paradigm in three experiments, participants’ neural activity was measured while they analyzed frequently presented male and female human stimuli and infrequently presented gender-matched doll-like objects. The infrequent doll-like objects were expected to trigger a late event-related neurophysiological response (P300) the more they were perceived different from the repeated, human stimuli (i.e., the oddball effect). In Experiment 1, the oddball effect was significantly smaller for objectified women compared to objectified men. Results of Experiment 2 confirmed that this effect was confined to objectified depictions of women. In Experiment 3, no semantic references to the human-object divide were provided, but objectified women were still perceived more similar to real objects. Taken together, these results are the first to demonstrate that the perception of women, when objectified, changes in essence beyond the metaphor.

Sexual objectification is a widespread phenomenon characterized by a focus on the individual's physical appearance over his/her mental state. This has been associated with negative social consequences, as objectified individuals are judged to be less human, competent, and moral. Moreover, behavioral responses toward the person change as a function of the degree of the perceived sexual objectification. In the present study, we investigated how behavioral and neural representations of other social pain are modulated by the degree of sexual objectification of the target. Using a within-subject fMRI design, we found reduced empathic feelings for positive (but not negative) emotions toward sexually objectified women as compared to non-objectified (personalized) women when witnessing their participation to a ball-tossing game. At the brain level, empathy for social exclusion of personalized women recruited areas coding the affective component of pain (i.e., anterior insula and cingulate cortex), the somatosensory components of pain (i.e., posterior insula and secondary somatosensory cortex) together with the mentalizing network (i.e., middle frontal cortex) to a greater extent than for the sexually objectified women. This diminished empathy is discussed in light of the gender-based violence that is afflicting the modern society.
