Emotion recognition in pictures of facial affect: Is there a difference between forensic and non-forensic patients with schizophrenia? Background and Objectives: Abundant research has demonstrated that patients with schizophrenia have difficulties in recognizing the emotional content in facial expressions. However, there is a paucity of studies on emotion recognition in schizophrenia patients with a history of violent behavior compared to patients without a criminal record. Methods: Emotion recognition skills were examined in thirty-three forensic patients with schizophrenia. In addition, executive function and psychopathology was assessed.
Facial expression, size, and clutter: Inferences from movie structure to emotion judgments and back

The perception of facial expressions and objects at a distance are entrenched psychological research venues, but their intersection is not. We were motivated to study them together because of their joint importance in the physical composition of popular movies—shots that show a larger image of a face typically have shorter durations than those in which the face is smaller. For static images, we explore the time it takes viewers to categorize the valence of different facial expressions as a function of their visual size. In two studies, we find that smaller faces take longer to categorize than those that are larger, and this pattern interacts with local background clutter. More clutter creates crowding and impedes the interpretation of expressions for more distant faces but not proximal ones. Filmmakers at least tacitly know this. In two other studies, we show that contemporary movies lengthen shots that show smaller faces, and even more so with increased clutter.
Facial expressions are used by humans to convey various types of meaning in various contexts. In this mini review we summarize findings on the use and acquisition of facial expressions by signers and present a unified account of the range of facial expressions used by referring to three dimensions on which facial expressions vary: semantic, compositional, and iconic. Humans perceive facial expressions as conveying meaning, but where do they come from and what exactly do they mean? Based on observations of facial expressions typically associated with emotions Darwin hypothesized that they must have had some instrumental purpose in evolutionary history. For example, lifting the eyebrows might have helped our ancestors respond to unexpected environmental events by widening the visual field and therefore enabling them to see more.
