We examined whether combined motor or spatial polarities could influence accuracy in two mathematical operations. Four experiments were conducted and showed that, when two corresponding polarities were activated, accuracy in multiplicative operations was greater than when non-corresponding polarities were activated, whereas no effect was found for additive operations. These results were established with motor cues (Left/Right and Arm Extension/Flexion, as behavioral approach-avoidance tendencies) and perceptual spatial cues (Left/Right and DOWN/UP cues). A polarity correspondence effect was established and proposed for multiplication. A combination of polarities was associated with a corresponding combination of numerical digits, assessed with mathematical operations, such as multiplication.
Several studies have shown that social judgement may be defined by two dimensions, competence and warmth. From a functional perspective, embodied theories have proposed that warmth may be associated with physical distance, whereas competence may be connected to a vertical motion (UPWARD/DOWNWARD). Two main studies were conducted to examine if approach-avoidance and vertical motion could influence affective judgements about traits representing these two social dimensions. Valence judgements about warmth traits that were moving towards the subject resulted in more positive judgement than when they were moving away (approach/avoidance). Furthermore, competence traits were judged more positively when they moved in an UPWARD direction, compared with when they moved DOWNWARD. A metacognitive account of confidence is offered to explain how cognitions about warmth and competence are connected to the physical world.
In this research, we examined whether emotional valence could correspond to a continuous lateral bias in space, according to a mental metaphor that establishes the mapping between a concrete domain (space) and an abstract one (valence). Because acting with one's dominant hand is associated with fluency and positive valence (the bodily specificity hypothesis, or BSH), we asked strong right-and left-handers to perform two spatial location tasks using emotional faces with seven levels of valence. We hypothesized and showed through two studies that, according to the BSH, extreme valenced stimuli (as compared to moderate and weak ones) would be located more at the extremity of a horizontal line, according to the correspondences between handedness and the different valences of the stimuli. This research establishes that spatial and continuous mapping of emotions was obtained while controlling for motivational direction.
Following metaphorical theories of affect, several research studies have shown that the spatial cues along a vertical dimension are useful in qualifying emotional experience (HAPPINESS is UP, SADNESS is DOWN). Three experiments were conducted to examine the role of vertical motion in affective judgment. They showed that positive stimuli moving UPWARD were evaluated more positively than those moving DOWNWARD, whereas negative stimuli moving DOWNWARD were evaluated as less negative than those moving UPWARD. They showed a valenced congruency effect, but an alternative hypothesis in terms of MORE is UP and LESS is DOWN was also examined. Finally, fluency mechanisms were investigated to confirm that relationships between affect and verticality were in accordance with a valenced congruency effect.
Several recent studies have supported the existence of a link between spatial processing and some aspects of mathematical reasoning, including mental arithmetic. Some of these studies suggested that people are more accurate when performing arithmetic operations for which the operands appeared in the lower-left and upper-right spaces than in the upper-left and lower-right spaces. However, this cross-over Horizontality × Verticality interaction effect on arithmetic accuracy was only apparent for multiplication, not for addition. In these studies, the authors used a spatio-temporal synchronous operand presentation in which all the operands appeared simultaneously in the same part of space along the horizontal and vertical dimensions. In the present paper, we report studies designed to investigate whether these results can be generalized to mental arithmetic tasks using a spatio-temporal asynchronous operand presentation. We present three studies in which participants had to solve addition (Study 1a), subtraction (Study 1b), and multiplication (Study 2) in which the operands appeared successively at different locations along the horizontal and vertical dimensions. We found that the cross-over Horizontality × Verticality interaction effect on arithmetic accuracy emerged for addition but not for subtraction and multiplication. These results are consistent with our predictions derived from the spatial polarity correspondence account and suggest interesting directions for the study of the link between spatial processing and mental arithmetic performances.
