![]() However, recent research has started revealing aftereffects in which test stimuli are only conceptually related to the adapting stimulus. Aftereffects are also typically constrained to a common sensory dimension, such as when a moving adaptor influences the perceived motion of a test (Barlow & Hill, 1963). the brightness of lights, or the volume, pitch or frequency of a tone see Clifford et al., 2007, for a review). Usually, perceptual aftereffects are quantified by giving people prolonged and repeated exposure to a specific stimulus, and then measuring changes in response to a range of stimulus intensities (e.g. Our results suggest the implied motion aftereffect produces a bias in decision-making, but leaves perceptual processing unchanged.Īn outstanding question in perception research is whether our thoughts, desires, emotions, or cognitions can change how our sensory systems operate. In Experiment 2 (real motion), we find equal changes to decisions and confidence. In Experiment 1 (implied motion), we find support for decision-level changes only, with no change in subjective confidence. We therefore used subjective confidence as an additional measure of the implied motion aftereffect. Since both categorical decisions and subjective confidence are informed by sensory information, confidence can be informative about whether an aftereffect probably results from changes to perceptual or decision processes. Equally possible, however, is that inferred motion changes decision processes, but not perception. This finding could indicate that inferred motion direction can penetrate sensory processing and change perception. ![]() Play around with it! I’m sure you’ll end up wondering how you managed without it.Viewing static images depicting movement can result in a motion aftereffect: people tend to categorise direction signals as moving in the opposite direction relative to the implied motion in still photographs. There’s still so much more that you can learn about the pick whip, but even the fundamentals I’ve described here can be enormously beneficial. Now, you can parent any of the individual transform properties to any layer you want. You can actually parent any of the individual transform properties between any layers you want to. If you drag that from one layer to the opacity of the layer above, you can now effect the opacity of both layers by just controlling the one. You can see in the screenshot below that there’s also a pick whip icon on each layer next to the opacity property. There’s a solution to this and it’s fairly simple. However, in the example I’ve just used here, you cannot control the opacity value of these layers using the null object. Opacity Here, you can’t control the opacity value of the layers using the null object. One thing to note is that the layers will rotate around the anchor point of the null object, not their own anchor points. Once you have done this, you can simply animate all the layers using the null, as shown in the screenshot below. If you select all the layers you wish to animate, you can drag the pick whip from the top layer to the null object, and it’ll parent all of them to it. Rather than animate them all individually, you can simply parent them to a null object and add the keyframes to that layer. In the screenshot below, you can see that I’ve got multiple layers that I want to animate in unison. The pick whip really comes into its own, though, when you start working on more complex projects. The shape layer is now moving with the text layer. The screenshot below shows me parenting the shape layer to the text layer using the pick whip, resulting in the shape now moving with the text. When you have parented a layer to another, it’ll take on any changes in scale, position, and rotation that the layer it’s parented to goes through. There’s a pick whip icon located on each layer, as shown below. It allows you to “parent” one layer to another. The text has moved while the shape layer has remained. If you have finessed your keyframes on your text layer using the graph editor, it will be quite laborious to create the exact same keyframes on the shape layer. You can see in the screenshot below that the text has moved without the shape layer. Let’s explore what it does and how to use it.Īll too often, you create a nice animation on a text layer using keyframes, before realizing that you want a shape to move with the text so that the shape and text move together. The Pick Whip is a motion graphics game-changing tool in Adobe After Effects.
